Sharp AR-M257 Generating pattern

[lenovos]

Pattern on AR-M257.pdf I think that I have seen this before. Customer had called and said that machine was randomly putting marks on copies and prints.

I made copies and sure enough some of them had this on them. I also sent prints from computer and also had pattern on some of them. I reseated memory and sim card on print controller. Problem seems to have gone away. I think that I have seen this before and thinking that it turned out to be laser. But can't quite remember.
If the problem returns I will let you know.

Thanks

If it returns, I'd replace the memory. Cool pattern! Thanks for the sample. =^..^=

It does very closely resemble a laser pattern, ditto what blackcat said; followed by checking the laser as you mention.

Though possible, I'd count it as unlikely. Usually lasers fail catastrophically, consistently. =^..^=
