Canon 1726 on inkjet printer: maintenance cartridge is full
Risk level
Low
Usually safe to check without specialist tools.
Urgency
High
Quick answer
Support code 1726 on a Canon MAXIFY means the maintenance cartridge, which collects waste ink from cleaning, is full. Printing stops until you fit a new one (MC-G01 on the GX7000 series) using the replacement steps in the manual.
Safety first
Stop and check this first
- Do not touch the terminal or the opening of the maintenance cartridge; Canon states this clearly in the replacement steps.
- Remove only the maintenance cover and its coin screw as the manual describes; leave every other screwed cover on the printer closed.
Safe checks you can perform
- Check the level in the hint menu
- Swap in a new maintenance cartridge
- Bag the used cartridge without spills
Leave these tasks to a qualified professional
- Do not attempt this professional task: Canon service if a new cartridge is rejected
- Do not attempt this professional task: Ask Canon about unusually fast filling
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Canon service if a new cartridge is rejected
What they doWhen the maintenance cartridge is new, correctly inserted and 1726 still shows, Canon's authorised service should inspect the printer.
They must show youthe cartridge status reading on the screen and a test print once finished.
In writingwhat was inspected or replaced and why, whether warranty applies and the case number.
Ask Canon about unusually fast filling
What they doIf cartridges fill far sooner than expected, Canon support can review cleaning frequency and usage habits with you.
They must show youthe dates of your recent cartridge swaps and how many cleanings you have run.
In writingthe usage advice given and the enquiry number.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check the level in the hint menu
- Who:
- you, with the printer switched on.
- How:
- on the HOME screen tap the hint icon and open Maintenance cart. info.; it shows the estimated used space and a Replace option.
- Result that matters:
- confirming the warning really concerns the maintenance cartridge before buying anything.
- If the indicator shows the cartridge as full:
- get the MC-G01 replacement ready.
- If no cartridge information appears:
- note the code and make sure the cartridge is seated.
- Evidence to keep:
- a photo of the maintenance cartridge information screen.

Swap in a new maintenance cartridge
- Who:
- you, following Canon's official procedure.
- How:
- unpack the new cartridge and its bag, remove the coin screw from the maintenance cover and lift the cover off by the finger hole; pull the old cartridge out holding its top, push the new one straight in until it stops, refit the cover and turn the screw clockwise.
- Result that matters:
- the printer recognising the new cartridge and printing again.
- If 1726 clears once the cover is back:
- the consumable was the only issue.
- If the warning stays with a new cartridge:
- take it out and reinsert it straight without forcing.
- Evidence to keep:
- the swap date and the box of the MC-G01 cartridge fitted.

Bag the used cartridge without spills
- Who:
- you, as soon as it is out.
- How:
- do not turn it upside down or rest it on the desk; seal it straight away in the plastic bag supplied with the new one by tying the opening, and keep your hands out of the printer.
- Result that matters:
- no ink on the desk, on your hands or inside the machine.
- If the bag is tied tight:
- dispose of it under local rules.
- If ink has escaped:
- wipe it with a cloth and avoid touching the terminal or opening.
- Evidence to keep:
- nothing special beyond noting any leak during the swap.

What it means
In the MAXIFY GX7000 series list of support codes, Canon defines 1726 as a full maintenance cartridge, and the only remedy it gives is to replace that cartridge. The GX7000 manual treats it as an owner replaceable consumable and gives a step by step procedure. Canon notes that how full the cartridge is when the error shows depends on where and how the printer is used. Other models with a maintenance cartridge may word the message differently, and the code by itself points to a used up consumable rather than proving a fault.

Symptoms and causes
Probable causes · in order
- Maintenance cartridge has reached capacityCommon
Canon's stated cause for 1726 is that the cartridge holding waste ink is full and must be swapped before the printer will print again.
Evidence: Canon MAXIFY GX7000 series support code 1726
- Earlier nearly full warning was not acted onPossible
Canon advises getting a new cartridge as soon as the screen says it is nearly full; leaving it means the printer eventually stops with this code.

- Heavy cleaning or demanding usage patternPossible
The manual says the cartridge condition at the time of the error depends on location and usage, so frequent cleaning cycles fill it sooner.
