Replace Cathridge I have an HP 2840. It would not copy or print. The Ready light would not come up. It says "Replace cathrige". Ihave replace the black toner but to one of the color toner. Do you think replacing the color toner would get it to work?

Re: Replace Cathridge

The front panel tells you witch toner cartridge should you replace. If a supply memory error ocures then the cartridge should be replaced or exchanged with a new one. The imaging drum unit is also consumable. for "Joe 50" - there are 4 toner cartridges in the printer.

We recently switched to Comcast and now our printer is not working. It says that it is on, and ready, but nothing happens when we try to print. We have an HP Color LaserJet 2840, and we use it for faxes,...

It seems that the connectivity b/w the printer and the computer is not through. Is it a wired or wireless printer? When you switched to comcast, did you made any changes to the wired connection with printer?

The hp color laser jet 2840 does not print. message "50.2 fuser error" appears

HP recommended checks: 1. adequate 120 VAC power supply, 2. Remove Fuser Assembly, wait 5 minutes and then reseat. 3. Reset the printer to Factory Default settings (remember to copy down the IP address, mask and gateway numbers first).

While this may solve the problem, it is much more likely it's time to replace the fuser. Cost is approx $125 if you buy it online. Just do a Google search on HP 2840 fuser.

This link will show you where your fuser is and how to remove and replace it.

Engion error

Based on prior experiences, it looks like it is the laser scanner that is bad, I have had some engine board go out too, but it should be 1 of the 2.

HP 2840 ready yet prints only a white page

Did you resolve this issue?
If not check that the Scanner bulb is lighting. If not check the cable from the scanner to the formatter and seated correctly. The scanner or the formatter board may be bad.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
