For a while now I've been taking the cartridge out and softly shaking it to squeeze more pages out of it -- then replacing the cartridge. It came time to replace the cartridge. I took the old one out, and double checked it with the new CF258X cartridge and they seem identical. I slid the new cartridge in and it would NOT go in far enough to allow the printer cover to close. It seems well seated on both sides of the cartridge, but it protrudes about 1/2 inch -- blocking the closure of the cover. I tried several times -- thinking I wasn't holding either the cartridge or my tongue correctly. No Go. So, I picked up the old cartridge and slid it back in. SAME PROBLEM! The cartridge will not slide in far enough to allow the cover to close. The cartridge protrudes enough to block the cover release push button on the right side. In both cases -- with the old and the new cartridge -- it seems to "snap' into place and it seems well seated on both sides of the cartridge I've inspected the interior of the printer -- even using a dental mirror, and I cannot see any potential obstruction. I can't believe I'm the only one to encounter this problem, but my Google Fu fails to find any similar complaint. Search seems powered more and more by AI, and all I get is hits for the bog-simple cartridge replacement instructions: "Remove the old one. Slide in the new one". Anyone here ever have this problem?
