Printer Repair Questions? Ask IT Technicians for Answers ASAP
Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
The error code also indicates the waste ink absorber full. Now, the job of the waste ink absorber or purge unit is to collect the dripping ink from the cartridges after a print job, so that the ink do not damage any spare of the printer. The best solution for this problem is replacing the waste ink absorber pads from any repair shop, but before that you can try the steps below to reset the error code, if it works then, you can use the printer for few more days, but ultimately you have to change the pads.
Thanks Dick for the response, please let me know if you need any further information otherwise please remember to give a positive rating, as that is the only way I am compensated for my time and effort.
I believe I found the full instructions for resetting the 5B02 error, please try this - this should save you from bringing in for service:
If the printer does not turn on after these steps, please unplug it from the power outlet for 1 minute, then plug it back in. The printer should start.
Were you able to go through the steps I provided to reset the printer? Is the printer working now?
