Could be one of two things. Either there is a door or cover you are overlooking (very easy to do), or there is a switch actuator that either needs adjusting, or replacing. Try opening every cover and door you can find, and taking out the photoconductor unit, unplug it, and give it a good looking over (front, back, inside). Put photoconductor/toner unit back in, and close all covers FIRMLY. This is where I would start if it were me. Hope some of this helps!!!

HP 7210 All in One keeps showing a paper jam, but there isn't one. What should I do?


Turn off the Printer
Remove the Rear Access door of printer
Check if the Rollers have any dust/ bits of paper
Clean the rollers with lint free cloth ( upwards just like the paper is picked and rolled )
Close the rear access door
open the front access door
Move the Carriage ( while holds the cartridges ) manually 5-6 times from left to right side
Check if there are any paper pieces stuck
Close the front access door
Turn on the printer - It should work fine

In case it gives same issue -

Disconnect the power cord from back of printer ( while printer is on )
While holding the # and 6 key, Connect the cord back
Release the # and 6 button after 3-5 times
Follow the instructions on the screen to align the cartridge

NOTE : doing the # 6 reset will erase Fax logs, Speed dial # you have saved in the printer.

HP Officejet 7210 All-In-One Inkjet. Arrived at


In absence of another solution, I finally switched the Officejet off. No idea if that "trashed" the memory or anything else, but it's working again - for now.

I am surprised that nobody, especially HP, has a real answer (let alone a solution) for this problem, when the same question about the same model has been asked since 2007 or before! I'll keep hoping, because the consensus seems to be that the "Assert! Memeory trashed?" WILL happen again.

HI there,
Follow the steps below:
Step one: Close the print cartridge access door
1.Verify that the print cartridge access door is completely closed. It may appear to be closed, but if it is not completely closed, the error message will display. Verify that there are no obstructions blocking the door.
2.If you are unsure how to close the print cartridge access door on your model, consult your User Guide for more information.
Figure 1: Examples of closing the print cartridge access door (your model may vary)
f3e57be.gif If you have attempted to completely close the access door and the error still appears, there may be a problem with the door sensor and the unit may require service.

Step two: Service your product
If you have completed all the steps listed above and are still experiencing a problem, service the product.

Good Luck!!!
