Re: Dell 1600 paper jam 1 or no cartridge

Your unit is actually manufactured by Samsung. Most probably you have a bad paper sensor. As a technician, you will find these sensors on the power supply board (SMPS)or main board. If your are receiving tech support from Dell, please illustrate those guys on how to do their job.

Re: Dell 1600 paper jam 1 or no cartridge

I just went through the trouble shooting with Dell the other night. They offered to fix it but its actually simple pretty to fix yourself if you are at all mechanically inclined.

I'll do my best to explain the fix. First, verify that there is actually no paper jam (open all the doors, take out the paper tray, take out the toner/drum unit and visually inspect),

If none, chances are there is a little plastic piece inside the printer that has popped out. The little piece allows the printer to detect when a sheet is exiting the printer. When it pops out, its gives the printer a false reading which makes the printer think there is a paper jam.

So, onto the fix. Turn printer off and unplug the printer from all cables (power, USB, phone, RJ45, etc). Secondly, take out the drum/toner unit and place in a dark spot like a closet.

Next, with the back of the printer facing you, turn the printer over so that it is resting on its front. The bottom should be facing you, and the back of the unit should be pointing towards the ceiling. I will use this orientation when describing the following steps.

Most of the back of the printer is actually a removable piece held in place by 4 silver cross head screws. Two are near the bottom of the printer in fairly deep recesses. The top two are easily accessible. Using a regular cross head (not flat head) screw driver, remove the 4 screws.

Once removed, the entire back panel should lift right off. You will then see the inside of the printer. You are looking for a small, gray plastic piece with a spring attached to it. It will probably be loose in the back of the printer. Its approximately 1.5" long and is roughly S-shaped. One end is different then the other, with one end being relatively skinny and the other end having a sort of paddle shape.

This is the piece that has popped out and makes the printer think there is always a paper jam. If this piece is not loose and is properly secured in place then you have a different problem. Reassemble the printer and call Dell for a replacement printer.

If the piece is loose, pick it up but ground yourself to the printer by touching any metal in the printer. Try not to touch the various electronics inside the printer unnecessarily.

Looking at the back of the printer, roughly in the middle where the paper exits is a black bar with various rollers on it. Below this should be a piece of sheet metal, gray in color, running from once side to the other (left to right) of the printer.

Visually follow this sheet metal piece. Roughly in the middle (left to right again) should be a small rectangular opening. Immediately below this should be a little black plastic piece with two little arms sticking out towards you, with a third arm perpendicular to the first two. This piece will be mounted on a small beige/brown PCB.

This is the actual sensor that the gray S-piece popped out of. If you look at the gray S-piece, you will notice that it has two little round knobs, one sticking out on each side. These knobs snap into the small semi-circular feature on the top of the two arms. The third arm is where the spring on the S-piece pushes against.

So, take the gray S-piece and hold it so that the spring is on the left, the thick paddle part is pointing towards the bottom of the printer, and the skinny part is pointing towards the top of the printer (towards the scanner section).

The skinny curved section of the gray S-Piece actually hooks behind the black roller. Thread the skinny curved section of the S-piece through the rectangular opening in the sheet metal piece and hook it behind the black roller.

Next, locate the two knobs on gray s-piece with the arms on the sensor so that they align with the top of the arms. Ensure that the spring's free arm is also lined up with the third arm on the sensor. When lined up, push down with a a small amount of force. You feel/hear a faint snap as the piece clips onto place.

Check that the spring is properly located in its arm by pushing against S-piece to make it rotate. When you let go, it should spring back to its default position.

That's it! Reassemble the back cover using the 4 screws. Go finger-tight only. These screws are only tapping into the plastic so if you over-torque them you will strip the holes.

It sounds tedious, but it took about 5 minutes to fix and now the printer is working fine.

Re: Dell 1600 paper jam 1 or no cartridge

YES -- my printer was within the 1 yr warranty. When I walked through the problem with a Dell rep, the conclusion was . . . they sent me a new one and I returned [postage paid] the old one. My luck that I was within the 1 yr warranty period -- no clue aout those outside of it. Good luck.

Re: Dell 1600 paper jam 1 or no cartridge

You will see there are 4 contacts where the cartridge connects to the printer. These flimsy pieces of wire bend and the contact is not made with the cartridge. Eventually rattling doesn't work and the printer becomes landfill (since it is cheaper to buy a new one)

Believe it or not, the advice to "rattle"(very important word) the cartridge in and out worked for me. I had attempted removing and replacing it countless times with no success, but "rattling" it did the trick the first time...for what it's worth.

I have a total of 10 HP Color LaserJet 4650 printers, and 7 of them have the following problem: they jam at the fuser whenever a full-color picture, photo, or slide is sent to print (especially ones with...

This jamming has to do with third-party toner cartridges being used. I had this problem using Xerox toner cartridges and found that I would have no jamming if I used at least 2 hp-brand toner cartridges and the rest Xerox. I then used a different brand of 3rd party toner cartridges that would not jam as long as just the black cartridge was a genuine HP black toner cartridge. This issue has been confirmed even by the manufacturers of the generic toner cartridges. Hope that helps!

Troubleshooting common laserjet printers problems

In order to understand and troubleshoot a Laserjet printer, I think it is important to understand how the printer functions. Laser printers for the most part contain some standard assemblies: Toner cartridge, Laser Scanning Assembly, High Voltage Power Supply, DC Power Supply, Paper Transport Assembly, Transfer Corona Assembly, Fusing Assembly, Printer Controller Circuitry, and Ozone Filter.
A laser printer undergoes a six step process that helps form images on paper. The six major steps are:

1. CLEANING- This is the first step in the process in which a rubber blade inside the printer cartridge scrapes any toner left on the drum into a used toner receptacle inside the cartridge. A fluorescent lamp discharges any remaining charge on the photosensitive drum (the photosensitive drum or EP drum loses its charge when exposed to light).

2. CHARGING- A special wire called the charging corona within the toner cartridge located above the photosensitive drum receives a high voltage from the High Voltage Power Supply. This high voltage is used to apply a strong , uniform negative charge to the surface of the drum.

3. WRITING- The laser is turned on and scans the drum from side to side, flashing on and off according to the bits of information the printer controller sends as it communicates the individual bits of the image. Where ever the laser touches, the photosensitive drum's charge is reduced to a slight negative charge. As the drum rotates, a pattern of the exposed areas is formed, representing the images to be printed.

4. DEVELOPING- Now the surface of the drum holds and electrical representation of the image being printed. Toner can now be transferred to the areas that were exposed in the writing step. A metallic roller called the developing roller inside the cartridge now acquires a charge from the HVPS. The toner sticks to this roller because there is a magnet located inside the roller and because of the electrostatic charges between the toner and the developing roller. The developing roller rotates toward the EP drum, the toner comes between the the developing roller and EP drum and is attracted to the areas that have been exposed by the laser and the toner is repelled by the areas that were not exposed to the laser. The EP drum continues to rotate until the developed image is ready to be transferred to paper.

5. TRANSFERRING- The developed image into position. The controller notifies the registration rollers that the paper should be fed through. The rollers move the paper underneath the EP drum, and the transfer process can begin. The controller sends a signal to the corona wire or corona roller (depending on which the printer has) and tells it to turn on. The corona wire/roller then acquires a strong positive charge from the HVPS and applies it to the paper. Now that the paper is charged, it pulls the toner from the EP drum and the line of contact between the roller and the paper. Once the rollers move the paper past the corona wire, the static-eliminator strip removes all charge from that line of paper.

6. FUSING- This is the final step in the process where the toner image is made permanent. The roller push the paper toward the fuser rollers. The fuser rollers grab the paper and is now in control of the paper. As the paper passes through the fuser, the 180 degree fuser roller melts the resin of the toner, and the rubberized pressure roller presses it permanently into the paper. The paper continues on through the fuser and then exits the printer.

The following picture will give you a general idea of the process and components.



PAPER JAMS- These are by far the most common problem encountered by all printers at one point or another. Some common causes of paper jams are as follows:

1. The paper is wrinkled or has upturned edges, the wrong type of paper is used, the paper is not place properly in the feed tray (usually not even).

2. If paper jams start happening at a frequent rate then the problem could be a worn roller (which can be replaced and are not that expensive). The following pictures shows the rollers.



3. Anther cause could be related to the drive gear of the pickup roller, shown here:


If your printer is printing nothing but blank pages, then the toner is not being put on the paper. There are three major causes for this happening.

1. The toner cartridge could be empty or if you have just bought a new cartridge it is possible that you purchased a defective one. If you forget to remove the sealing tape the toner will not be able to be accessed properly by the printer.

2. The Corona Assembly could have a malfunction such as a missing or damaged corona wire. If this is the case the developed image will not transfer from the EP drum to the paper. The following is a picture of Corona Assembly:

3. Another cause is the High Voltage Power Supply. If the power supply does not charge the components with the proper voltages. Picture of an HVPS:


This usually happens with heavily used or older laser printers. The following could be causing the problem.

1. Toner may have been spilled inside the printer.

2. A chip or crack in the EP drum can be another cause which can cause a toner build up and can get stuck on one of the rollers. EP drum picture:


This can be caused by the following:

1. A groove or scratch in the EP drum.

2. A dirty Corona Wire which prevents a sufficient charge from being placed on the EP drum.


The number one cause is the following:

1. This usually happens when proper cleaning and maintenance is not performed on the printer. Foreign matter gets caught on the transfer Corona Wire.


This happens when you pick up a paper that has just come out of the printer and when you touch the ink, it smudges or smears.

1. The fuser could be malfunctioning or need replacement due to a burnt out halogen light inside the heating roller.

2. Dents or cold spots in the fuser heat roller can also cause the problem.


Ghosting is what you have when you can see light images of previously printed pages on the current page. Usually one of two things cause this problem.

1. Bad erasure lamps. This causes the previous electrostatic discharges to not be completely wiped away.

2. A broken cleaning blade. This causes old toner to build up on the EP drum and presents itself in the next printed image.


This happens when the print on the paper comes out like garbage and is not understandable or looks like some government secret code on the page. The following are usually the causes.

1. The printer driver software is not the proper driver for the printer or it is not configured for the correct page-description language (PCL or PostScript).

2. A bad formatter board. Remember the formatter board receives information from the computer and turns it into commands for the various components in the printer.


The following are some extra pictures to gain a better idea of some of the terminology used in this tip and get a better view of its components.

hi....take it to a tech to check about the system control chip... the control chip would have gone bad... and they will replace u with a new chip..or else Try manually moving the head carriage back and forth a few times!
Also check, if there isn't some piece of paper lodged inside, if yes try to remove it carefully!..

these are the possible solutions u can try out...

Prints faint copies

If the print rubs off the page, this means the toner is not being fused to the page. Fused......this is done by the fuser. This would have nothing to do with light print.

The dell (1600n and 1815n /1815dn) printer drivers has a toner saver mode, which can contribute to light print.

To turn Toner Save Mode off, (Windows XP) perform the following steps:
  1. Click the Start button, click Settings, and then click Printer and Faxes.
    The Printers and Faxes window appears.
  2. Right-click Dell Laser MFP 1600n, 1815dn, and left-click Printing Preferences.
    The Dell Laser MFP 1600n, 1815dn Printing Preferences window appears.
  3. Click the Advanced button.
    The Dell Laser MFP 1600n, 1815dn Advanced Options window appears.
  4. Click to highlight Toner Save.
  5. Click the drop-down list and change it to Off and click OK.
  6. Click OK.
One thing that you mentioned in your post "it takes the printer forever to warm up". The fuser does have to reach operational temperature in order for it to fuse the toner to the page. So it is possible that you are having fuser problems, because of the time it is taking for it to warm up. Another thing that can contribute to the warm up time is not plugging the laser printer directly into a wall outlet. This would be true for any laser printer, not just a Dell laser printer. The low voltage power supply is what works the fuser, along with sensors and other motors in the printer.

Replacing the fuser and or the low voltage power supply in this model of printer is not an easy task. If using a Dell branded toner cartridge and checking the toner saver mode does not fix the issue. Then you would be looking at more expense then the machine would possibly be worth.

Paper jam 2 - checked every area - cut equipment off and back on - still paper jam 2 - need service person asap.

there are 4 or 5 sensors through paper road:
1)paper input sensor near input roller
2)margin sensor between input roller and cartridge unit
3)transfer bell sensor between cartridge and fuser unit
4)fusing sensor before fusing
5)out put tray sensor
check all sensors if you can find out and check any paper jam there and check sensor stander at normal position, also check each sensor click ok(the micro switch ok) .
there is any sensor out of work should be showing paper jam.

Laserjet 4345 mfp paper jam

13.20.00 can be also caused be a jam near the fuser (the part of the printer that gets hot to make the toner stick to the paper). Remove the toner cartridge and take a look for small scraps of paper along the whole path. Also open the door on the back of the printer and look for paper scraps from there. If you see paper stuck in the fuser, do not use anything sharp to remove it, be careful not to scratch the surfaces.

Paper jam, Is this the fuser?

I have had the same problem. Changing the fuser is easy (about $85, and must be ordered through Dell) remove the 4 screws from the back, and you'll see the fuser. 2 screws, and 2 wires, and it slides right out.

Dell 1600n Cartridge Sensors messed up

the cause of this problem is a little spring sited in left side of feed sensor´s actuator and keep it on it´s right position: sensor actuated(off);if this little spring is out of position,feed sensor´s actuator go out of position and machine´s main board detects high(on) signal showing a paper jam message.

I have dell 1600 multifunctional jam 1/no cartridge

I have been having the same problem. I almost gave up on this printer. After careful analysis I noticed that if I pulled up on the cartridge while it was inserted and held it up (I took the door off and depressed the door closed button w/ a screwdriver) the printer would work fine.

I shimmed the front of the cartridge w/ a piece of rubber or folded up paper. There appears to be something in the back that doesn't make full contact if you do not do this. Now it works fine.

I haven't had any feed problems, but I kept my shim to the front right and made sure it doesn't go too deep.
