You've done everything but replace the formatter.
Can you look at the Event Log? Look for a 79.xxxx error. That is definately a formatter.
Is this a solid error, meaning does it appear when printer inits?
Remove the DIMMs and flash memory and network cable. And reinstall one by one until error reappears.
Do you have another 4345 that you can "borrow" a formatter from?

Hp laserjet p2015dn prints one page and then goes offline. i delete the job, then turn printer off. Sometimes, it will show online and sometimes offline. Also, when I shut printer off the light may stop...

Known issue with these printers. The formatters fail at an alarming rate. At one point HP was replacing them under an Extended Service Advisory, but they have discontinued that program. You could try calling and raising a stink and they might do something for you. Otherwise, check on Ebay, likely someone is selling used formatters.

How do i get this error cleared 49ff95 on hp laserjet m4345mfp

Hi, Well this problem could be due to a lot of things. If this won't with a power cycle then make sure there is nothing in the print queue, a corupt file could cause this. If nothing there then try a cold reset. I believe turn off then on when you see the memory start counting hold the number 6 down until the three lights turn on and stay on. (Something should be seen on the screen like disk intialize or something) push 9 until you see cold reset then hit 6 again.

Hp 2420 displays 53.07

The 53.07 error relates to Memory. Turn the printer off. Remove the right side cover. Remove any and all DIMM (memory) cards and printer/network cables from the formater board. The memory DIMMS are located behind the metal cover. Remove any Jetdirect Cards installed into the EIO slot on the back of the formatter.

With all accessories removed power up the printer and see of it comes to ready. If not, you need a formatter board. If it does come to ready, power it off and plug one peice that you removed back in and try again. Keep adding one at a time and powering up again until the error returns. When you get the error, the last added back onto the machine is the problem.

Here's a copy of the service manual to help with disassembly, troubleshooting and part numbers for ordering.

Hope that helps you. If so, hit me with a fixya!
