Direct answer
For the Canon MAXIFY GX7021, supply installation/venting, protective seals, nozzle/printhead output and driver document content should be separated. First, print the internal quality/nozzle page.
What this covers
- Canon MAXIFY GX7021 (4471C037)
- Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.
- The specific fault this record addresses: prints blank pages
What it does not cover
- ×The same symptom on a different Canon product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
Protective tape or packaging was left on a new cartridge
What separates it Blank pages immediately after installing a new cartridge or setting up a new printer.
How to confirm New cartridges ship with sealing tape or a clip that must be removed. This is one of the most common causes on a new installation and is entirely reversible.
- 2
The printhead is completely blocked
What separates it The nozzle check prints nothing at all, or nothing in any colour.
How to confirm A total blockage after long disuse is different from partial banding. See faded-streaked, and expect this to need a deep clean or head replacement.
- 3
The cartridge is empty or not seated
What separates it Blank pages with a low-supply message, or after a cartridge change.
How to confirm Reseat the cartridge until it clicks positively. A cartridge that is in but not latched behaves as if absent.
- 4
The document itself is blank or the wrong page range was sent
What separates it One document prints blank while others are fine.
How to confirm Print the printer's own internal test page. If that prints correctly, the printer is fine and the problem is in the document or the application.
- 5
Multiple sheets fed through together
What separates it One blank page alongside a correct one, with a full or fanned-out paper tray.
How to confirm Fan the stack and reload it squarely. Sheets sticking together pass through unmarked.
- 6
The wrong printer or a print-to-file driver was selected
What separates it Nothing appears at all, or blank output, with several printers installed.
How to confirm Check which device the job was actually sent to.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the printer's own internal test page also comes out blank — this separates the printer from the computer in one step.
- Whether a cartridge was changed or the printer newly set up immediately beforehand.
- Whether every document is blank or only one.
- What the nozzle check produces, on an inkjet.
Print the printer's own internal test page from its control panel
ReversibleA correct test page proves the printer works and moves the problem entirely to the computer or the document.
Check for protective tape or a clip left on a newly installed cartridge
ReversibleThis is the single most common cause of blank pages on a new printer or after a cartridge change.
Reseat every cartridge until it latches positively
ReversibleA cartridge that is inserted but not clicked home behaves exactly as if it were absent.
Print the nozzle check
ReversibleNothing at all from any colour indicates a total blockage rather than the partial banding of a clogged nozzle group.
Fan the paper stack and reload it squarely
ReversibleSheets stuck together pass through unmarked and produce a blank page alongside a correct one.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- 4471C037. Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.
- Type — BUSINESS refillable INK TANK all-in-one (MAXIFY)
- A business-class MAXIFY MegaTank AIO — refillable ink BOTTLES with PIGMENT inks (more water/smudge-resistant, business-document oriented) and high-volume features (large paper capacity, fast duplex, fax/ADF). Still inkjet, so the printhead can CLOG if unused.
- Pigment ink + volume
- Pigment inks suit crisp, durable documents; the tank system gives very low running cost for offices. Don't run tanks dry. Initial charging uses some starter ink (normal).
- Connectivity
- Wi-Fi/Ethernet/USB via the Canon app; 'offline' is usually a network/queue issue.
- Symptom boundary
- This record covers Canon MAXIFY GX7021 when it prints blank pages. A different symptom on the same hardware, or this symptom on a different Canon product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Stop for toner spilling inside the printer, and clean it with a damp cloth rather than a household vacuum.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Canon publishes this as "Blank pages on prints and copies (MF8080/MF8380)". Covers pages coming out blank on both prints and copies, which separates a print-path fault from a scan-path fault. Probed 2026-08-21: title-verified. What that article does not carry is the model boundary — it is written for a product line, and 4471C037 is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My Canon MAXIFY GX7021 output smudges or clogs.+
The MAXIFY uses pigment inks that are more smudge-resistant than dye — if it is smudging, make sure the ink is dry before handling and that you are using the correct paper type/setting. If output is faded or streaked, it is a printhead clog (still an inkjet): run the nozzle check and Cleaning/Deep Cleaning, and never let the tanks run fully dry. As a high-volume business tank printer, keeping it used and the tanks topped up keeps it reliable and very low-cost per page.
I just installed a new cartridge and now everything prints blank.+
Take the cartridge back out and check for protective tape, a plastic clip or a sealing strip that was not removed. New cartridges ship with sealing that has to come off, and missing it is by far the most common cause of blank pages right after a change. Then reseat the cartridge until it clicks positively home.
How do I know if it's the printer or my computer?+
Print the printer's own internal test page from its control panel — that bypasses the computer entirely. If the test page prints correctly, the printer, its cartridges and its paper path are all working, and the problem is in the document, the driver or which printer the job was sent to.
Does this answer apply to every Canon model?+
No. It is scoped to 4471C037. Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.
What should I record before troubleshooting blank pages or no ink?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing blank pages, no ink. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Avoid repeated deep cleanings that waste ink or overheat components.
