Question about Xerox Phaser 7700 Laser Printer
Our Xerox 7700 is giving a message that the Number 4 print cartridge is missing.
The cartridge is not missing.
The message appeared after a staff member replaced print cartridge number 2.
Any suggestions for fixing this?
In order to solve such a problem in your printer cartridge, you should take a flat blade jewelers' screwdriver along with a blade whose width is somewhat more extensive compared to the pads and place the blade side flat throughout the contact.
After that, drag the blade end throughout the contacts, from each direction, knocking down firmly with the flat.
You may experience blows as you traverse the pads.
It is to compel the ridges in the region of the holes back to the holes.
This procedure has proved to be of great help for most of the users who have experienced the "Print Cartridge Missing" error.

Solution: Fixed! Did not fix. TRY FIRST (Solutions without parts):
1. Door A not closed properly. - Open and close door A, then power cycle the printer and check for the error again.
2. The rails that the print cartridges slide in are misaligned or bent. - Remove the Transfer belt and all print drums, then check and re-align print drum rail guide. Then reassemble and verify proper operation.
