Thread: Vertical Lines Showing up in 4880

  1. #11
    Ok thanks
    I have the option of doing the head alignment from the printer itself or using the Adjustment program. Does it matter from which place it is done.?
    As well I have attached a photo of what looks be the encoder strip sensor. Can you confirm that it is this yellow/orange board in photo?

    do the head alignment from the printer.

    the encoder strip sensor is the part that goes over the encoder strip. I can't tell from this diagram if that is the sensor or not.

    Would cleaning the actual encoder strip work as possibly as well?

    I got you.. I see it now....

    Unless you actually see ink splatter on there, it's not going to be the encoder strip.

    Looks dirty for sure but no ink splatters.
    For the life of me I cannot find the part number for this encoder strip sensor for the 4880. Not on compass micro or anywhere else. Any thoughts?

    Um...Walker I think I have messed up the description of what is happening here. I am not in fact getting vertical banding but HORIZONTAL banding...Sorry I goofed up! The lines are in the same direction of the print head passing. What looks like is happening is that I get a clean nozzle print out but after some time while printing the drop outs come back. Is this a flushing/cap assembly issue then? Cleaned the wiper and asssembly thoroughly. Sorry for the confusion

    If the nozzles are all firing properly but you are getting banding this could be dampers that are full of crud or that you have simply not set the paper feed speed properly on the printer (this can be done on the printer's panel in the Custom Paper settings of the printer).

    Or is the other possible cause bad dampers? Compass micro sells dampers for $35 but you can get them from parts places for $4 a damper. What do you recommend in your experience?
