Ошибка 49 ff04 service error

That is very odd. So, to make sure I understand, if you disconnect all data cables and leave the printer powered ON, it will eventually get the 49 error? 

Make sure you’re plugged directly into a wall power outlet and not into a power strip, surge protector or UPS. Any one of these can cause strange problems. Make sure the power you have is good, clean, stable power and not fluctuating or has other high power demanding devices on the same electrical circuit (i.e. microwave, refrigerator, etc.).

Typically a bad formatter will get a 49 error at power up, not 30 minutes later, unless there is a power or data problem. Maybe try plugging it in at a friends house to see if it still fails.

Thanks for your reply. Actually, the error pops up after about only 10 minutes after the printer is switched on. I’ve had this printer for years, never had any problems with it. It used to be connected to the AC supply via a large APC UPS box, but  that UPS is now down due to battery failure, and haven’t gotten around to replacing the batteries as I have other UPS boxes to handle the network equipment that was also plugged into the unit with dead batteries.

The printer has been connected directly to the wall outlet. This is an old industrial park, and the AC supply is not all that great. The other UPS boxes go on battery due to over/under line voltage fluctiuations, maybe once a day for a few seconds. But the printer goes offline and pops the error message even when nothing is doing, as shown on the UPS box supply monitors. 

So, I dunno.

Well, if it was working well before your UPS went down and now it is having issues, it may be related to your power — but hard to say. I’ve not seen 49 errors related to power issues, but I can’t say it can’t happen. I’ve seen weird issues due to power or devices plugged into UPS, power strips or other such power outlets, and manufacturers recommend staying away from those, but maybe you need yours back. UPS’s will also filter noise from the line as well as compensate for power fluctuations. It may be that there is noise (electrical noise) in the power that is affecting your printer that won’t be evident unless checked with special equipment like an oscilloscope or other test equipment.

I’d say try fixing your UPS first and if it still fails, I’d try the formatter next. It’s odd though that it powers up OK, then 10 minutes or so later the error comes up. I’ve not encountered that symptom before.

Well, I had the printer turned off for a few hours — unplugged — and I plugged it back into the UPS. This was a week ago.

Since then no errors, performs perfectly! I believe that previously I had just turned it off, unplugged, immediately plugged back in. It sure seems to be like something «stuck» in the printer’s software/firmware somehow.
