Hi I have a HP Officejet L7850 Printer with a "Rear Door is Open" error. I have checked the rear door and I do see the contacts on the door is damage and can not make a proper connection with the sensor. Can I bypass the sensor?

Hi,

Turn off the printer.
Open the rear access door.
You need the clean the rubber rollers with lint free cloth. There could be dust particles stuck on the rollers. Cleaning it with lint free cloth ( clean upwards exactly like the rollers roll after picking up the paper )
Close the rear access door firmly.
Check if the error message goes off.

If you still find the error message, follow the steps below :

Disconnect the power cord from back of the printer ( while the printer is powered on )
While holding the # and 6 key on keyboard, connect the cord back.
The printer will go through alignment process. Complete the alignment.
*Note : Doing this reset, you will loose any fax logs or settings set on printer

The printer should work fine. If the issue does not resolve, it could be hardware issue.

Hi there,

Good Luck!!

Thanks for using FixYa!!

Turn off the Printer
open the Front access Door, Check if there is bits of paper or dirt on the ROD that moves the Cartrige/carriage.
Move the Carriage freely 5-6 times from left to right ( it should move smoothly )
Remove the Cartridges, Clean the contacts on the Cartridge ( golden Contacts)
Open the Rear Access door, Clean the Rollers with lint free cloth.
Close the Rear access door and front door
Power on the Printer. If the grinding noise continues, Unplug the power cable from back of printer ( while printer is on ) and while holding the # and 6 button, connect it back.
It should go thru alignment process and the grinding noise should be gone. If it doesnt, probably.. its time for new printer of HP again.

Hi

Paper jams can be real or false. The unit may report a paper jam when there is not any jammed paper, however, the solution to a real paper jam or a false paper jam is the same. WARNING: Jammed paper must be removed using the rear access door and the power cord must be disconnected or a carriage jam or mechanical damage may occur. Do not remove jammed paper from the front of the unit.

1. Turn off the HP product and turn it so the back of the unit faces you.
2. Disconnect the power cord from the back of the all-in-one. The power cord must be disconnected to allow the paper feed rollers to turn freely.
3. Locate and open the rear access door by pressing in on the left side tab 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.
5. 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.
6. From the rear access door opening, remove the jammed paper.
7. 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.
8. Reinstall the rear access door.
9. Reconnect the power cord to the unit and turn the unit on. If a carriage stall occurs after clearing the paper jam, resolve the carriage stall.

Preventing paper jams The following information will help prevent paper jams from occurring:

• When loading paper in to the paper tray, push it in until it meets first resistance. Do not continue pushing the paper in. If the paper is pushed too far in, more than one page is picked and paper jams result. This is the most common cause of paper jams with the HP Officejet 410 series.
• 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, 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 - one year, clean the paper feed rollers with a rag slightly dampened 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.

Please do rate the solution as FixYa and revert for further assistance.
