Hello, and thanks for letting me join.
I have an old NP1550 which has recently died. I'd like to get it up and running again as I can't really justify the purchase of a replacement.
Used to work fine on auto lightness, but more recently had started to produce copies which were too dark, but evenly so, though this could be overcome by the manual override slider.
Tonight, one copy OK, but the next all black followed by E220 error, which I believe points to the scan lamp or its controlling circuitry.
Turning on and off clears the error on re-boot, but it returns shortly after pressing the start button, again producing an all black copy.
I've not looked inside it yet; it resides in the house that I'm in the process of moving from to a new home in a different town.
I was actually using it to make copies of house deeds etc. which are too big for my A4 USB scanner.
Any ideas where to begin; I'm mechanically and electrically reasonably competent, but have no experience of photocopier servicing.
Fortunately I have found a copy of both parts and servicing manuals, so at least I have a start. I also have basic test equipment in terms of meter bench PSU etc, but my scope's just died as well.
I'm hoping the copier's gradual decline, before tonight's expiry, will point someone more experienced in the right direction.
I've also found spare lamps and a DC controller on line, but I'd rather not just swap things out at random.
Many thanks in anticipation
Bill
