I just purchased a used HP 3600N printer. The front door/panel closes fine when there are no toner cartridges in it. However, when I put cartridges in it, the door no longer closes. The seller offered this advice:
"Please make sure that the toner locking clips are in the unlocked position before installing the toner. There is a cartridge lock for the four toners located on the side of the printer where the mechanism pops out to engage drive with the toners. We hope that this helps. Please let us know what happens."
However, I do not understand these instructions. I'm looking for someone who would be willing to do a skype or other web-video session and walk me through the steps.
I will pay $10 flat fee for successful help
