Re: HP LaserJet M1522nf freezes up and will not print

Glad it worked for you. I knew it would as I have baked over 50 of these boards and have only had to re-bake 3 of them over the last few years. This issue was caused by cold solder joints that develop on the main processor and baking re-flows the solder to correct the problem. Also works on P2015 formatters and jet direct card models 610N and 615N.

jaltman,

 

I have the exact same HP freeze problem.

 

I looked at the manual and can't find and locate how to remove the formatter board in question.

I have the M1522NF.

 

Can you please elaborate?

 

thanks,

 

Rob

jaltman,

 

Never mind.

 

By doing a google search for "Where is the formatter board located for HP M1522nf" I found a great YouTube that shows everything step by step.

Re: HP LaserJet M1522nf freezes up and will not print

can you please send me a copy of the service manual for the M1522nf?

The link in the posted message does not direct me to the manual.

 

I would like to try the baking solution.

 

Thanks.

Four years later this fix seems to continue to work. This printer has been a work horse for us and just now (2015) started giving us the problems mentioned previously. 

 

I found youtube videos of the process where some forgot to remove the memory and failed. (The devil is in the details!) I've seen some suggest unsoldering the battery so I did that simple task and resoldered after the baking. 

 

The printer seems to be functioning properly now. If it goes through the day without a restart we will call it a 100% success. UPDATE: 1 week later the printer is working like new! 

 

Thanks for posting the fix and thank you HP for keeping the thread alive!!!!
