We have a c451 that keeps putting squares on the copies or scans. I've been told its a bad ram stick but was wondering if it could be anything else or if anyone knows of a temp fix while I'm waiting for the new stick to come. I tried some laptop memory that matched the faulty stuff exactly except for the make but the copier just spits out its dummy.
Heres what the copies look like say 1/8 will do this not exact same but very similar patterns.
Thank for any help,
