Quick answer: what ink does the Canon PIXMA MG6320 use?

The Canon PIXMA MG6320 uses six individual ink tanks: PGI-250 pigment black plus CLI-251 black, cyan, magenta, yellow, and gray. High-yield PGI-250XL and CLI-251XL tanks fit the same slots, and you replace only the color that runs out. The gray tank is what separates this model from the five-ink PGI-250 printers.

Common questions about Canon PIXMA MG6320 ink

Standard or XL: which should I buy?

XL. PGI-250XL is rated for about 500 text pages versus 300 for standard, and the CLI-251XL colors roughly double the standard yield, so the cost per page drops sharply. Because the tanks are separate, you can also buy XL only for the colors you use most. See Is XL ink actually worth it? Standard vs. XL with real numbers.

What other printers use PGI-250/CLI-251 ink?

The five-ink models are the PIXMA MG5420, MG5520, MG5620, MG6420, MG6620, iP7220, iX6820, MX722, MX922, and MG5422. The six-ink models that add a gray tank are the PIXMA MG7120, MG7520, and iP8720. Every size of the shared colors fits all of them, so one stock of cartridges covers several printers.

Will other Canon cartridges fit the MG6320?

No. PGI-270/CLI-271 (used by the PIXMA MG5720, MG6820, and TS5020) and PGI-225/CLI-226 (used by the MG5320 and MG6120) look almost identical but have different chips and notches. Always match the number printed on your current cartridge.

Why are there two black cartridges?

They do different jobs. The larger pigment black (PGI) prints sharp, smudge-resistant text on plain paper. The dye black (CLI) is used for photos and glossy paper, where pigment ink would sit on the surface. Both must be installed, and on plain-paper documents the pigment black does most of the work.

Are compatible or remanufactured cartridges safe for the MG6320?

Yes. Canon lists no firmware updates for the MG6320 and we found no reports of it refusing non-Canon tanks. Using them doesn't void your warranty under U.S. law. The printer may show a message about a non-genuine or refilled cartridge, and ink-level monitoring may be switched off for that tank; choose OK or Continue and print normally.

How do I replace the ink in the MG6320?

Turn the printer on and open the cover; the print head holder moves to the replacement position. Press the tab on the empty tank and lift it out. Remove the new tank from its bag, pull off the orange protective cap, insert it front end first, and press the top until it clicks. Match the color labels on the holder. The tank's lamp lights red when it's seated correctly. Walkthrough: How to replace the ink in a Canon PIXMA printer.

Why won't the MG6320 recognize a new tank?

Make sure the orange cap and any film are removed, press down on the tank until its lamp lights, and check that it's in the slot with the matching color label. If the lamp stays off, remove the tank, wipe the contacts with a dry lint-free cloth, reinstall it, and power-cycle the printer. More fixes: Printer says ink cartridge not recognized: how to fix it.

Why are MG6320 prints faded, streaky, or missing a color?

The print head is built into the printer, so a clogged nozzle won't be fixed by a new tank alone. Print a nozzle check, run a cleaning, and if gaps remain, a deep cleaning; let the printer rest a few hours if it still streaks. If lines look jagged or doubled rather than faded, align the print head. Guides: How to clean Canon printer heads, Faded or streaky prints: causes and fixes, and our print head alignment guide.

Can I keep printing when one tank is empty?

Canon printers stop when a tank runs out. On many models you can override the warning by holding Stop for about 5 seconds, but Canon cautions that printing with an empty tank can damage the built-in print head, so replace it as soon as you can. Keeping a spare pigment black on hand avoids most downtime.

What does the gray tank do?

The CLI-251 gray tank improves black-and-white photos and smooth gradients. Replace it like any other color when it runs out; the printer won't print without it.

Does the MG6320 work on Wi-Fi?

Yes. It connects over 2.4 GHz Wi-Fi and works with the Canon PRINT app. If it keeps dropping off the network, make sure your router broadcasts a 2.4 GHz band. It also has an Ethernet port, which is the steadier choice if Wi-Fi keeps failing. Setup help: How to connect a printer to Wi-Fi.

What MG6320 owners ask

These are the questions that come up most for this printer on retailer Q&A pages, Canon's support community and owner reviews, answered in our words.

Can I put letter-size photo paper in the top tray?

No. The upper cassette takes small photo sizes only (4×6 and 5×7). Letter-size photo paper goes in the lower cassette, which holds 125 sheets of plain paper.

Can it print on CDs and DVDs?

Yes. A slot in the upper cassette feeds printable CDs, DVDs and Blu-ray discs.

Why does it sometimes sit for minutes before printing?

Imaging Resource measured warm-up and ink-cycling delays of one to five minutes. Opening the print head area, even just to look at the tanks, is a common trigger.

Can I print from a USB flash drive?

No. It has memory card slots for SD, CompactFlash and Memory Stick, but no USB port for thumb drives.

Can I still get drivers from Canon?

Canon has retired the MG6320. Its support page says product support and driver updates are no longer provided, so keep a copy of the driver you have installed.

MG6320 quirks worth knowing

• The output tray opens by itself when a print job starts, so keep the front of the printer clear.
• It prints two-sided automatically, but it has no document feeder. Copies and scans are done one page at a time on the glass.
• Imaging Resource saw a slight blue cast in black-and-white prints and slightly pink light skin tones.
• It launched in December 2012 at $199 as one of Canon's six-ink photo all-in-ones; the gray tank is what sets it apart from the five-ink MG5420 and MG6420.
