The Clever Supplies compatible Canon CLI-42 Cyan ink cartridge replaces the Canon CLI-42 and fits the PIXMA PRO-100 — the only printer in this family. It is rated at about 600 pages; our cartridge is filled to the same specification with dye ink and carries a new compatible chip that reports ink levels to the printer.
The cartridge carries a new compatible chip that reports ink levels to the printer. If a firmware update ever causes a recognition warning, reseating the cartridge and restarting the printer clears most false alarms; anything that still refuses to print is covered by the lifetime warranty.

Frequently Asked Questions
What part of a photograph does the cyan tank actually handle?
Cyan builds the blues and blue-greens: open sky, ocean and lake water, and the cool side of green foliage. In the Canon PIXMA PRO-100, this CLI-42 cyan cartridge matters because skies and water are mostly gentle gradients, where any weakness in blue shows up immediately as uneven, patchy tone.
Does this cyan fit any printer besides the PRO-100?
No. It is made for the Canon PIXMA PRO-100 only, the single model in the Compatible Printers list for the whole CLI-42 family. A different PIXMA model uses a different cartridge family, even if the tank shape looks similar. Match the CLI-42 name on your current cartridge before you order.
Why do skies look wrong first when cyan runs low?
Low cyan shifts blue areas toward magenta and red, so a clean sky turns slightly purple and water loses its fresh blue-green. The change is gradual, which makes it easy to blame the file or the screen. Print a small proof and check the sky first before adjusting your image.
How many pages is cyan rated for, and how should I read that number?
About 600 pages, below the black rating in this family. Ratings reflect standardized test pages, not full-coverage photographs, so a portfolio of seascapes draws cyan down much faster. Use 600 pages to compare cartridges, and use the printer's level report to plan a replacement before an important run.
How do cyan and Photo Cyan divide the work between them?
Think of this tank as the full-strength blue and CLI-42 Photo Cyan as the diluted version for pale areas. Full cyan lays down saturated sky and deep water; the photo version fills highlights and faint gradients where full-strength drops would look grainy. They are separate slots, replaced independently.
Will ink levels show correctly after I install this cartridge?
Yes. A new compatible chip is fitted, so the printer recognizes the cartridge and reports levels normally. Canon firmware updates can occasionally change recognition behavior; if a warning appears right after an update, reseat the tank and restart once. Anything that still refuses to print is covered by the lifetime warranty.
My cyan is empty but the other tanks are fine — what should I do?
Replace just this slot and keep printing with the others; individual replacement is the economic advantage of an eight-tank system. The colors most often checked alongside cyan are CLI-42 Magenta, which balances its cast, and CLI-42 Yellow, its partner in greens. Leave every healthy tank undisturbed.
Is this an original Canon cartridge?
No, it is a Clever Supplies compatible CLI-42 cartridge, built to the same specification and filled with dye ink, which is why it costs less than the original. If you want to refresh everything in one order, the CLI-42 Set of 8 includes this cyan plus all seven other colors, each chipped and individually sealed.
What happens if this cartridge leaks or prints poorly?
The Lifetime Warranty covers it: a leaking, unrecognized, or poor-printing cartridge is replaced or refunded, and returns are accepted for 1 year. Tell us what the print showed — a color cast description helps us confirm whether the tank or a setting caused the problem, and we will put it right.
