Customer brought in this unit for check , alignment seems to be off , making double letters , seems to only be on black . Cleaned timing strip , checked carriage movement and and path for obstructions , ran Alignment , both Auto and manual , pulled print head and hard flushed and checked contacts and re-seated it , attempted FW update . Print quality still the same . I know its a low cost machine and likely just need to replace it , but we sold a bunch of them and may see this issue more , looking for quick fix if its out there . See sample attached , check out the PGBK line . Thanks in advance , Ark .
