erase HP LaserJet 4250n printer memory

[george101010]

HP LaserJet 4250n Printer. Because of it storing a memory error inside the printer, it will not print anything from my computer. It will print its own internal source reports such as a configuration page just fine. I have found that some LaserJets will cancel their memory by turnig it off and holding the OK button while turning it back on. This printer has a green checkmark button but it doesn't do that. This printer must have a special way to clear the internal memory but I don't know what it is. Please help. There is no problem with the cartridge.

Try running Cold Reset or NVRAM to see if it helps.

Before doing that you may want to print out Configuration Page from 4250n's front panel to keep all the settings.

Thank you very much EAST2100. To initialize the NVRAM on step 5, arrow up.......to where? It goes through several different up choices and one is COLD. I already did the COLD but I believe you are correct and it is also time to use the NVRAM I am just stuck at arrow up. Please advise.

That's all coming from HP 4250's Service Manual with no doubt.

It's different from 4200/4300 with 4250/4350.

You need to power on first when seeing memory counting then press "Select" button then doing what next ......

If you did it wrong you won't get it right.

Look into the manual and do it right again it will work.
