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.

Re: Color Photo Conductor Unit
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.

When you banding vertical do you mean Across paper feed direction OR With paper feed direction?
If its across the feed direction the chances are thje issue remains with the individual printhead, Print out a quality maintenance print to find which Printhead is not working as well as wanted, then replace ( or clean using the plotters control panel under image maintenance.
Errors along the feed direction can be down to Software/ Main Pca /
is it on printing or in copier mode? if in copier mode is it via feeder or on the platen glass? if via feeder see if your slit glass is clean. on top of the platen see to it that your mirrors inside are clean, if so here comes the Photo conductor units and the fuser units.
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.
Nozzle check must perfect for perfect output. There are tranversal lines at vertical straight lines that represent same point of head micro piezo. If tranversal lines no clog at all, but vertical straight lines not perfectly straight, the result not good (like horizontal white banding). Check it? Head aligment is for vertical banding. If your result is horizontal banding, you don't need to realign head. It's caused by some residual at the output of head sprayer. So, the spray of ink not straight to paper. Try to print with photo/best photo.
Hi. the problem is the print head, maybe is clogged or damage, try this remove the cartridges , and the print head and submerge the print head in hot water for 3 minutes, dry the print head and reinstall it, if problem persist replace the print head.
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.
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.
