Color Photo Conductor Unit

I have noticed vertical lines across my printed photos. I did check the Photo Conductor Units Type 125 and found concentric circles along two of the color drums. Can this be corrected and how or is it time to replace the Color Photo Conductor. Also, what causes these rings on the drum? The printer isn?t that old. I am still on my first replacement of toner. Hope you can help. Thanks

The vertical line that you saw is an indication of either it is normally worn out, or something has caused the scratched, by any material ( PC drum is very sensitive to any material and can easily damaged or scratched any solid and unwanted dirt inside) see you actual meter reading. if it falls on the first thousand copies or print then it might have caused by a scratched, if it falls beyond the PM parts repalcement then there is nothing you can do but to replace this.

sometimes you can swap the colors, by the affected color use the yellow drum unit to the affected drum, the vertical would not that be obvious.

This evening I bought a new HP Photosmart C4780 printer. I am trying to print photos now and the photos are being printed with small vertical lines across the whole photo. How do I get rid of them?


> I bought a new printer

Take it back, and get one that does work correctly.

> VERTICAL lines ACROSS the whole photo

Hold the paper in "portrait" mode, not "landscape" mode.
Are the lines HORIZONTALLY-ACROSS the paper,
or VERTICALLY-DOWN the paper?

If those lines are WHITE and HORIZONTAL,
then some of the many ink-jets inside the print-head are *CLOGGED*.
Run a "print-head-cleaning-cycle" to try to unclog it.
Or, exercise the WARRANTY, and get it replaced.

Strange lack of color lines


These are actually called PCU ( photo conductor unit) and yes they can be required to be changed frequently at times. I work on a lot of Ricoh printers and this is a common issue.

Printing problem


Pull out the color photo conductor unit. If you see lines on any of the green drums replace the color photo conductor unit. You can also get color registration errors if the transfer unit is scrached. my first recomendation is to look at the color pcu unit and replace it if you see any lines on it. Also pull out and inspect the black pcu unit.Let me know what you find.

Not printing all text


If you blank stripes in the vertical plane, it would suggest that toner or other foreign material has got onto the laser lens. Remover the toner and photo conductor units and look for the glass panel above the laser unit. Clean this with a tissue or soft cloth. You should find this gets you away. If not then the photo conductor is the next suspect to replace.

Vertical streak near left edge of printouts....only affects black portion of print image


Where best to look will depend a little on the nature of the smudge. If what you're looking at is white, then you might just have a little heap of toner or paper dust on part of the LED array that paints the picture onto the photoconductor drum (look for a narrow unit that stretches full width, adjacent to the drum. Dark marks may, if you're lucky, be down to dirt on charger wires. Both respond well to cleaning with a vacuum and a soft cloth (be very gentle if cleaning the wires). I would be inclined to trust the existing photoconductor unit unless you know it's been abused (e.g. by leaving it lying around in daylight) or the coating on the drum is visibly damaged. A.
