Phaser 7800 printing with line

[Laura_1992]

Hi everyone,

We purchased the Phaser 7800 at the beginning of this year. The last few months when printing SRA3 a line (vertical) appears on the side of our prints (please see below photo). We have tried cleaning the LED sensors but this didn't fix the problem. We don't get any lines on A4 prints. 

Does anyone know how I can solve this problem? It's very frustrating and is affecting the quality of our prints. 

Thanks in advance for any help :-)

Hi,

It is possible to be from one drum cartridge. To see that swap the drums between them (all 4 are the same).

Hi Gabiene. Thank you for your reply and advise! How do I best go about swapping the drums?

Just now I see your image. If you are sure that you have a good cleaning of the LED's, it looks like there is a debris in one developer housing so you will need a tech to remove it or to replace the developer material for affected color.

Hi Gabienne. It doesn't appear to be related to a specific colour, because the lines also appear in B&W prints.

We live in the island of Bonaire (Dutch Caribbean) and cannot get a tech to easily come and help us. Not sure how to proceed... :(

It looks like to be from magenta. The best way to check is to print separately C/M/Y/K at 50% coverage.
