    HP Deskjet 9300 - All leds blinking

    Hi there,

    I would like to successfully repair an HP Deskjet 9300 but everything I have tried until now does change nothing. Everytime all the printer leds are blinking, but sometimes I can get it to work. I can print a couple of pages and suddenly it stops and starts blinking again the three leds. I have already checked voltages, cleaning all, oiling sparingly. Ink Carts are new. Service station is clean and dry. The encoder strip is in good conditions and clean.
    One thing I have noticed is that the head moves shortly one side and shortly the other side and then the leds start blinking.
    The leds are not blinking at the same time, they do that in a asynch manner.
    The error trap sequence is C 00E 04 02. The last code 02 means "error_pen_trident_a2d_incomplete".

    I would be glad to have some advice or help, thanks.
Working...
