About Canon 045 & 045H Toner Cartridges – 1246C001–1243C001

Castle Ink sells compatible Canon 045H high-yield toner cartridges in every color: black (1246C001), cyan (1245C001), magenta (1244C001) and yellow (1243C001), plus a black-and-color 4-pack. The 045H fits the same slots as the standard 045 (1242C001–1239C001) and holds roughly twice the toner. They fit the Canon Color imageCLASS MF632Cdw, MF634Cdw, MF635Cx and LBP612Cdw. Each cartridge is newly manufactured to the original specifications and tested before it ships. Orders placed by 4 PM ET ship the same business day, shipping is free over $50, and every cartridge is covered by our 1-year 100% satisfaction guarantee.

Chip note: these cartridges ship with a working chip so the printer reads toner levels normally. If the printer shows a “non-genuine” or “supply problem” message, press OK or Continue and it prints normally; keep automatic firmware updates off (why that matters).
