Konica 7022 f28-1 error

Unit has been unused/in storage for about one year. It was previously networked.
In trying to start the unit up, it does its self-check, the normal screen comes up, it begins to warm up, then it defaults to a F-28-1 code. In process of doing a thorough breakdown and cleaning. I have experience with Docucenters, but not with this brand.

Is F-28 a power supply error?
Is this related to network settings?
What can I do at start-up to reconfigure?
What should I look for when doing the cleaning?

Konica 7040 trouble code 51-4


This 51-4 code is directly related to the write unit. It can either be a bad lazer index control board mounted externally to the side of the write unit or a bad M5 polygon motor. It is better to replace the whole write unit. Konica P# 26WA-6500.
On a side note, the 7020 write unit can be used in place of the 7022 write unit & is far less prone to failure then the 7022 write unit! 7020 write unit Konica P# 26NA-6500.
