Power the printer off and pull the plug.On the right side of the printer is an access panel, slide it back to disengage it. Now you should be looking at a metal cover. Pull it out from the front to open it and lift it off its hinges. There will be at least one memory DIMM facing you. If there are two, remove the lower one. Power the printer up. If it initializes, good. That means that the DIMM you pulled is bad. If it still fails, power down, pull the plug and remove the other DIMM. Power up. If it works the 2nd DIMM is bad. Power down again and put the 1st DIMM you removed in the slot that the 2nd one came out of. power up and order another DIMM. Don't forget about the covers!

How can tell if the ink level is low? hp 2420


Cartridge comes along with memory, the information of estimated ink/toner levels will stored in this memory(Depends upon the cartridge model yield will varies). When printer performs the printing, memory count will comes down, when its reaches the minimum count printer will display the message of "low ink/toner/remain pages" levels, once its reaches to '0', display will changes like "replace the cartridge"...But there is no electronic component or mechanism to measure the ink/toner levels in the cartridges.Only estimated levels only printer can recognizes..

HP Laserjet 4345MFP
Backlight on printer display does not light.
Counts up the 256MB memory then HP logo (3 sizes) appears (just visible)
The 3 lights keep cycling on the display. Thats it, does nothing else.
It has been left overnight and continues to display the logo and cycling 3 lights.
Rear DC Cont Fan is turning. No other fans or activity with machine.
When ADF/scanner/mfp or hard disk are disconnected it does recognise this and throws an error and asks for reboot.
I have tried cold reset, nvram init. and hard disk init. but no difference.
Your thoughts?

HP 4650 turns on, does the count up to 128MB, HP logo appears then it stops and only "initializing" on display.


Remove the Jetdirect card and try it. These tend to cause this fault. If not, possibly down to the formatter board

First time using my hp color laserjet 5550


We need to start with turning the machine on not connected to the computer.
Disconnect machine from computer.
turn machine on
if locks on memory count 128mb turn off.
If machine has a jetdirect card (network card I/O) installed remove it.
Turn machine on.
If it comes READY you found the problem.
If you are not using on network reconnect to computer and try again.
If there is no network card let me know.
hope this helps
