Fixing The “Call For Service H4-00” On Sharp Or Any Digital photocopier

There was no Sharp shop in this part of the country, so I had to find an alternate solution. Funny enough, the local technician I gave the copier to service, couldn’t pinpoint the real problem. I did love the photocopy machine because of its quality in printing, so I wanted it to work as it was.

I called another local technician, and he finally fixed the machine back to the way it was :).

After six months eight days of using it, I encountered a simple but funny problem. One of my employees was printing out some documents, and after the last printout, it showed “call for service H4-00” I thought the copier had broken, but I browse the problem and learned that it is natural to meet such problems.

If you have a digital scanner like the Sharp AR-M207 you will know that someday, you might have little issues like the “call for service H4-00 or L4-11”. Calling a technician might be unnecessary or kind of expensive, so doing it yourself might be the right choice.

Note: You will need to have a fast finger for it to enter the simulation mode.
