Question about Lexmark Optra T612n Laser Printer

1 Answer

Lexmark Optra T612

On the underside of the printer there is a shaft to which an arm is attached with the paper pickup rollers. On the shaft is a plastic moulding to which a spring is attached which keeps the paper feed rollers up when not printing. The moulding broke and the spring detached and the feed rollers dropped into the paper tray which is how we became aware of the problem. I found a way of attaching the spring however it hasnt fixed the problem. When I try to use the printer I now get a message to replace the paper tray. Is there something else which has broken or is it a matter of resetting something.

The broken part is called the bell crank arm part number 56P1228 this is very common. If the printer isn't recognising your tray, remove it and check the little plastic fingers on the left side (half way down the tray) and the metal springs in the printer (left side) which the tray pushes on to.

How to resolve constant jam error 241 on Lexmark x652de MFC printer?


Double check to make sure roller shaft isn't 'locked' in both directions or spinning in both directions. If the shaft moved to the right a bit, it might be spinning in both directions. If it is, Grab the pick arm in one hand and push the roller shaft a little to the left. The shaft should spin in one direction but not the other. I am a Lexmark tech and have had this happen quite a bit on the 64X and 65X models.

How do i clean the rollers



Introduction Your printer requires minimum routine maintenance. This chapter explains the following tasks
  • Cleaning the printer
  • The toner cartridge
  • Extending toner cartridge life
  • Clearing a TONER LOW message
  • Replacing printer parts
Cleaning the printer To maintain print quality, thoroughly clean your printer:
  • Every time you change the toner cartridge
  • After printing approximately 6,000 pages
  • Whenever print quality problems occur
Clean the outside of the printer with a lightly water-dampened cloth. Clean the inside with only a dry,lint-free cloth. Observe the warnings and cautions that follow the cleaning tasks on the following pages. Caution To avoid permanent damage to the toner cartridge, do not use ammonia-based cleaners on or around your printer.
Printer Cleaning Tasks Before you begin these steps, turn the printer OFF and unplug the power cord. Caution Do not touch the transfer roller (black sponge-rubber roller) with your fingers. Skin oils on the roller can cause print quality problems.
If toner gets on your clothes, wipe it off with a dry cloth and wash your clothes in cold water. Hot water sets toner into fabric.
Warning Avoid touching the adjacent fusing area. It may be HOT
  1. OPen the printer's top cover and remove the toner cartridge
  2. with a dry lint-free cloth, wipe any residue off the Paper Access Cover (it has a green handle) and the adjacent silver metal strip.
  3. Wipe any dust or dirt off the black plastic Paper Feed Guide with a dry, lint-free cloth.
The Toner Cartridge see the printed book pending update of this page Extending Toner Cartridge Life see the printed book pending update of this page Clearing the TONER LOW Message see the printed book pending update of this page User-Replaceable Parts Some worn parts can be replaced by the owner. See Chapter 8, "Solving Printer Problems", for descriptions of the difficulties that can indicate when to replace a part. Warning Switch OFF and unplug the printer before replacing parts. Failure to do so may result in personal injury or damage to the printer. After switching the printer OFF and unplugging the power cord, allow the printer to cool for 30 minutes before replacing the parts.
Unless specifically noted, replacement is the reverse of removal. Always carefully observe the position and alignment of the part you are removing; this is your best guide to replacement.

13.2 paper jam/open tray error, but its not. It doesn't make the right sounds when initialising, no motor running.


Hello There,

After working with HP for quite sometime,

here is what i recoimmend.

1.Ensure that paper trays are loaded properly, so that paper can feed from the tray
2.Check the input area for obstructions, such as paper in the path or visible damage to the paper path near Tray 1.
3.Remove the print cartridge and lift the green handle attached to the metal plate underneath to check for paper in the paper path.
NOTE: Try swapping the tray and print cartridge with one from different printer, same model. Determine if issue follows the tray or the print cartridge.
4.Ensure that paper is feeding correctly from the appropriate tray (try using a freshly opened **** of paper).
a.Inspect the pickup assembly by removing the paper tray in question to look inside the printer.
b.Locate the rubber roller with a purple, plastic hub (paper feed roller).
c.Locate the paper pickup assembly that is directly behind the paper feed roller. The paper pickup assembly consists of a shaft with four half-moon shaped rubber and white plastic rollers attached to it.
d.Rotate the shaft to locate the half-moon rollers and ensure that it turns easily.
e.Locate the black plastic coupler shaped like a dog bone that is immediately to the right of the shaft .
f.If either the pickup assembly or the coupler is missing or damaged, the printer will need to be serviced.
5.Do not fan paper to separate, bend the **** into a U shape to break the sheets free from one another.

NOTE: If the steps listed in this document do not return the printer to a READY state, service may be required. Contact the HP Customer Care Center for more information
Please feel free to leave a testimonial if this works and please do not forget to click 4 thumbs.

13 Paper Jam - but there is no paper inside!


I have a long solution (possibly) to your issue:

Error 13 Paper Jam
  • Paper jams can occur in 3 places: Entry, registration and exit.
  • If the paper isn't picking up out of the paper tray, visually inspect the pickup roller. If it looks shiny, replace it. You should also replace the separation pad as they work together. On the 4L/4P/5P/6P the pickup roller has a plastic shaft that breaks. You'll have to replace the whole pickup assembly. This requires major disassembly of the printer. Check our printer repair kits for your model printer. If you don't see it listed, email us.
  • If you have an HP 4/4+/5 with an optional 500 sheet feeder that's jamming, check the balance knob adjustment. Center it with a full **** of paper for proper operation.
  • If the paper is jamming at registration or anywhere between pickup and exit it could be a number of things. Check the paper path for torn bits of paper or label residue. On the II/III series, remove the metal registration guide plate (2 screws) and check underneath it. If the pickup rollers are moderately worn, the paper will stop just short of the registration roller. On the 4L/4P/5P/6P remove the screw holding the oblique roller assembly (Inside front of printer) and pull out and inspect the assembly and the area under it. On the HP 4/4+/5 pivot up the metal plate and check underneath it. Check the roller assembly on the left side for torn scraps of paper (a flashlight or torch is necessary).
  • Make sure paper cassettes are firmly seated, corner tabs aren't bent. Some trays have lifting springs that could pop out if tray has been dropped.
  • On HP IIP/IIP+/IIIP printers if the paper scrunches up at the toner cartridge you'll need our Inside Accordion Jam Repair Kit.
  • Check your software settings in the program you are attempting to print from. Do you have the correct paper size specified? If you have a different paper size than what is in the tray, you'll get a paper jam.
  • Exit jams are frequently caused by exit sensors. These sensors are typically mounted on the fuser assembly or adjacent to it. They are plastic arms that block and unblock an optical sensor. The arms can get stuck or knocked out of place when clearing paper jams. The optical sensors can also get dirt blocking the photo cell. Clean the sensor and check for free movement and proper installation of the sensor arms.
  • On HP II/III series exit jams are mostly caused by worn gears. The best way to troubleshoot this is to defeat the door interlock (see door interlock photo on troubleshooting page). Press down on the arm on the top right of the fuser. Initiate a test page. While holding down the arm, press one of the metal cartridge detect switches just below the door interlock. Watch the movement of the gears. You will get a 51 error because the door is open. Recycle power to get rid of error. There is an arm gear on the lower right of the fuser that can shed teeth. There is also a 14 tooth gear below the large gear on top of the fuser. You can also manually rotate the large gear and check for binding or crunching. If that happens, then replace the 14 tooth gear. On the door, there are some delivery coupler gears that mate with the fuser and drive the exit roller. Check the gears for excessive wear. Replace if necessary. If the paper gets almost all the way out and jams, replace the exit roller or the exit roller assembly. If the error occurs after fuser replacement, check and see if the connector on the left of the fuser is properly mated with the one in the printer.
  • On HP IIP/IIP+/IIIP printers if the paper has accordion folds on the bottom and jams on exit, order our Top Output Accordion Jam Repair Kit.
  • On HP 4/4+/5 printers the most common cause of exit jams is the exit assembly. Order our 4/4+/5 Exit Jam Repair Kit. Exit jams in the fuser can be caused by a broken fuser drive gear or a broken gear on the fuser. Remove the fuser and check the gear inside the printer for broken teeth. Manually turn the gears on the fuser and check for smooth operation. Check the paper exit sensor arm for proper mounting and free movement.
  • Check to make sure the rear door is closed on the printer. Open doors can cause 13 paper jam indications.
  • On the 5L/6L check the registration sensor arm below the pickup roller. Also check the exit sensor arm (bottom center of the fuser). These arms frequently get stuck or dislodged clearing paper jams. On these printers, if you are experiencing frequent paper jams, order our 5L/6L Multi-Sheet/No Feed Repair Kit
All this comes from:

Good luck with it, I love the HP LaserJet 4 series of printers. I used to warm my coffee on the top of the fuser when I was doing large print jobs :-)

If this information helps, please give me a rating, thanks!

Laserjet 1320 will not pick paper


Paper misfeeds and failure to pickup the paper are both common symptoms of a worn pickup roller. This roller is on the bottom of the printer as shown in the attached picture.
1_19_2012_3_22_12_pm.gif
With use the rubber tire gets smooth and can't grip the paper enough to pick it up and push it into the printer. The roller kit is easy to install yourself and will get the printer back going as good as new. You can get the roller kit here:

Dell 1700 laser printer wont load from tray only manual


This is a common misconception with this model printer. People say that the roller does not drop down to pick up the paper. With this model printer, the pickup rollers ONLY drop when the paper tray is inserted. If you look on the top left edge of the paper tray towards the front of the printer you will see 1 1/2" to 2" section where the plastic edge is raised about 1/2 an inch. This raised part in the plastic actually serves as the mechanism for dropping the pickup rollers on to the paper.

So... The solution DOES HAPPEN TO BE cleaning or replacing the pickup rolers/tires. Rubber rejuvinator is the best for cleaning the rollers, but buying a whole can that you may only use once or twice may be a bit overkill. You can try cleaning them with soapy water if you do not have any rubber rejuvinator. DO NOT use alcohol, as this will dry out the rollers and shorten their lifespan even more.
