topic TR8660 changed PGBK ink and cleaned and aligned head - still streaky in Desktop Inkjet Printers https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/TR8660-changed-PGBK-ink-and-cleaned-and-aligned-head-still/m-p/466784#M70297 <P>Recently my TR8660 started missing horizontal black lines. Cleaning the PGBK ink fixed it for a time, then if the printer wasn't used for a few days the missing lines came back until another clean was done.<BR />I've changed the PGBK ink cartridge (genuine Canon) and done a clean and deep clean, aligned the print head both automatically and manually. There are still horizontal streaks about every inch - even the head alignment instruction sheet had streaks through the printer pictures at the top.<BR /><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="IMG_20240311_0003.jpg" style="width: 706px;"><img src="https://community.usa.canon.com/t5/image/serverpage/image-id/50791i135C1F444877D9BD/image-size/large?v=v2&amp;px=999" role="button" title="IMG_20240311_0003.jpg" alt="IMG_20240311_0003.jpg" /></span></P> Mon, 11 Mar 2024 05:04:19 GMT bluebottle 2024-03-11T05:04:19Z TR8660 changed PGBK ink and cleaned and aligned head - still streaky https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/TR8660-changed-PGBK-ink-and-cleaned-and-aligned-head-still/m-p/466784#M70297 <P>Recently my TR8660 started missing horizontal black lines.
