Print the browser test
Select the paper size, keep scale at 100%, and print the Complete sheet at Normal quality. This tests the browser, driver, connection, and printer together.
Canon printer guide
Use this browser sheet to test the whole print path, then compare it with Canon’s built-in nozzle check or quality report to pinpoint whether the fault is in the printer or the computer.

8 pt — Fine text should remain crisp, evenly filled and easy to read without halos, feathering or broken strokes.
6 pt — If this line is legible and consistent, your printer is resolving small type well.Print it right
A scaled or economy-mode print can look like a printer fault. Start with a controlled print before changing ink, toner, or hardware.
Select the paper size, keep scale at 100%, and print the Complete sheet at Normal quality. This tests the browser, driver, connection, and printer together.
Open Maintenance in Canon PRINT or IJ Printer Assistant Tool and choose Nozzle Check or Print Check Pattern. On panel models, look under Setup or Maintenance.
If both sheets show the same defect, focus on ink, toner, nozzles, alignment, or hardware. If only the browser sheet fails, focus on the app or driver.

The issue is likely in that ink channel, cartridge, tank feed, or printhead—not the browser.
Verify ink and venting, run a nozzle check, then one cleaning cycle if the pattern has gaps.
Printer hardware can reproduce the pattern. Driver, application, color mode, or connection is more likely.
Reset print preferences, update the correct model driver, and test from another app.
The printhead alignment or paper feed calibration may be off on an inkjet.
Run automatic or manual Print Head Alignment from the Maintenance menu.
On imageCLASS models, a toner cartridge, drum, transfer component, or fuser may be involved.
Use the model’s quality report and service guidance; do not run inkjet cleaning routines.
A nozzle check is more specific than a colorful photo. Each printed line corresponds to part of an ink channel. Missing or broken segments justify a normal cleaning; a perfect nozzle check suggests the problem is more likely alignment, paper, driver settings, or color management.
Canon laser models do not have inkjet nozzles. Pale vertical bands, background toner, smears, and marks that repeat at a regular interval point toward toner distribution or a rotating imaging component. Use the built-in quality report before replacing supplies.
FAQ
You can print the browser diagnostic above, or open the printer’s Setup/Maintenance menu or Canon utility and choose Nozzle Check, Print Check Pattern, or a quality report. Wording varies by model.
It shows whether each ink channel is firing through the printhead. Broken lines or missing sections indicate blocked nozzles, poor ink flow, or an empty channel.
A good built-in check suggests the printer and ink path work. Reset the document’s print settings, confirm the correct driver and paper profile, and try another application.
Yes. Use the black, color, grid and text patterns for imageCLASS and other laser models, but follow laser-specific toner, drum and fuser guidance rather than nozzle cleaning advice.
