Kyocera FS-1350DN error “Call service F020:”

with 5 comments

I’ve owned a Kyocera FS-1350DN for a few years and am very happy with it. The only negative is that when printing several documents at a time the printer will sometimes pause for a few minutes between documents. I assume that this is due to the relatively modest 128Mb of memory that the printer is shipped with as standard.

Official Kyocera memory modules are expensive with even the 256Mb module priced at £250. However, I recently noticed a German retailer, PHS-electronic GmbH, selling a compatible 512Mb memory module on Amazon UK for a mere £30 and decided it was worth a try.

I was very impressed that the memory module arrived the next day and immediately installed it. I switched the printer off and removed the power cable as advised in the FS-1350DN user manual, installed the module, and then turned the printer on again.

Unfortunately, it displayed an error message within a few seconds:

Call service

I checked the manual but this specific error code is not described. I cycled the power but the error message appeared again. I removed the memory module after switching the printer off and unplugging the power cable and re-inserted it and realised what the problem was. The memory slot on the internal PCB seems to require that you slide the module into place holding it approximately parallel with the PCB. However, if you do this then it won’t be seated correctly.

You need to insert the module at an angle of around 30 degrees to the PCB and push it in firmly. You will feel it move positively into the slot. It can now be hinged downwards so that it is flat against the PCB and the metal retaining clips engage the module.

Once I’d done this the printer started successfully and the management web page shows that the module is recognised in memory slot 1:
