SOURCE: error 13-jam paper HP Laser 4+

HP LaserJet 4, 4m, 4 Plus and 4m Plus Series Printers - False Error Message 13 PAPER JAM ISSUE: After clearing all jammed paper from the HP LaserJet 4, 4m, 4 Plus, or 4m Plus series printer, the display still reads 13 Paper Jam . Even after cycling the power off and then back on, the error remains. SOLUTION: Open the rear door of the printer. There is a paper sensor near the upper right hand corner of the fusing assembly (just below the right edge of the long yellow warning sticker on the fuser) that can cause paper jam error messages even when there is no jammed paper in the printer. Toggle the thin black plastic lever up and down to make sure it is not stuck or sticky. The lever should be in the down position before closing the back of the printer. If the lever is stuck or missing, the printer will generate a false paper jam message. Hope it will help you !

hp tells me to do the following
does this help you ?



Issue While printing, copying, or receiving a fax, a paper jam occurs. If the jammed paper is removed incorrectly, other problems may occur. Clearing paper jams Remove the jammed paper by following the steps below: WARNING: Jammed paper must be removed using the rear access door to avoid mechanical damage. Do not remove jammed paper from the front of the all-in-one.

1. Turn off the HP product and turn it so the back of the all-in-one faces you.
2. Disconnect the power cord from the back of the all-in-one. CAUTION: The power cord must be disconnected to allow the paper feed rollers to turn freely and avoid mechanical damage.
3. Locate and open the rear access door by pressing in on the left side tab to release the catches and then pulling the door toward you. Figure 1: Removing the rear access door
4. Inspect the pressure rollers on the rear access door and verify that they are clean and turn freely. Clean the rollers if needed with a soft towel lightly moistened with water. If the rollers do not turn freely, replace the rear access door. Click How to Buy on this page to order replacement parts.
5. From the rear access door opening, remove the jammed paper.
6. Remove the remaining paper from the paper supply tray. Discard any paper that is damaged or crumpled and then re-stack and reload the paper into the paper supply tray.
7. Reinstall the rear access door.
8. Reconnect the power cord and turn on the all-in-one.

• Never use paper that is wrinkled or damaged in any way.
• If you are having problems using paper that has already been printed on once (recycling), replace it with fresh paper.
• Remove and then reinstall the rear access door. Verify that the access door is fully locked in place. The paper can skew if the rear access door isn't locked.
• Every six months to one year, clean the paper feed rollers with a rag lightly moistened with clean water. Over time the paper feed rollers accumulate dust and do not function as well as they once did.
• When printing envelopes, tuck the flap into the envelope and crease the folds before printing.

hi,

the issue that you have might need to change some settings from the printing properties. WHen you hit on PRINT, a box will open, right? look on the top right of that box, you will see "PROPERTIES" or "Preferences" just click on it, then another box will open. Click on Printing Shortcuts tab, try to review the settings. And if you want to print using the main tray, it should set it to Automatic select or Main tray. And make sure that it sets to General Printing. But if youre going to print a photo, you will have options there to choose what type of paper when you click on that, the settings on the paper size, paper source, etc. will change also. For paper source, make sure that it sets to Photo Tray.

If you will be able to open printing preferences, all options are there, you just need to read and choose which settings you want to use.

Thank you so much.

Rollers do not turn on!
Rollers are driven by a motor.
How is the printer telling you this information? (does the PC give an error, or the printer flash lights)

Does the paper make it out of the machine?

Is this "Rollers in the Back" the Fuser Unit?

is The Fuser unit is going bad,
if you open the back top cover, where it gets real hot, where the paper exit's, you should see two rollers, one orange, one either brown or black.. if that orange roller is damaged, has crease's, or covered with black toner, if the paper jams here alott, you probably need a new fuser unit. there is a pm kit available which includes the fuser and rollers, transfer, etc, which this site might have

Check the gear on the left side of your printer where the disk encoder strip is attach,the gear is not holding the metal shaft your need to replace that gear. The problem is in the inner hole where the shafting is attached.
