HP Deskjet 1200C

I recently took our office printer apart for cleaning and lube. Everything was fine as far as the parts went(no broken or missing pieces). Here is the problem...the printer will not initialize. All I get is the self test and then flashing amber lights on the display(manual feed,check paper and check cartridges). I have no manual but it has been assembled properly and it has new cartridges. Help!!!!

IT sounds as though the white ribbon cable became dedacthed form the machine... either that or the sensors are not sensing the cartridge another possibility is that the machine has lost it's home position. there should be a a long metal looking thin stip it goes the whole width of the printer it is about 1/4 tall it looks like a metallic band or could appear to be plastic.... this goes under the carriage to the cartridge it is encoder strip it has to be under the carriage it goes inbetween a grove on the backside of the carriage make sure that it is seated in there properly .... make sure you turn the power off when doing this put the carriage in the center push SLIGHTLY down on the encoder strip and then wiggle it away from you then towards you as you let up pressure on it you should feel it pop into a groove..... BE VERY CAREFULL DOING THIS THOUGH IF YOU PUSH DOWN TOO HARD ON IT IT WILL BREAK..... Once you have it seated power the unit back up it should be fine now IF the carrriage is either not moving or banging up against the right or left hand side then chances are it is the encoder strip or the ribbon cable....

If this doesn't work then the printer will most likely need to be serviced

 Thank you, Brian. Your answer was sraight and to the point. I did indeed have my encoder strip oriented correctly but the ribbon cable had pulled just loose enough to break the connection. The retaining clip has a broken lock and placing the rear cover caused it to pull loose (and of course you can't see this with the cover on). Prints like a dream now. Love those HP's. They are practically indestrutible. Thanks again for your good advice and in such a short time since I had posted my question!!
you are welcome I am glad that you were able to get it fixed on some printers you cannot fix those ribbon cables because the solder them to the boards so it is a good thing it was not in your case.. :) have a good day
