Print head alignment is off (misaligned text or lines)

Symptoms

• Vertical lines that should be straight look jagged or doubled
• Text looks slightly offset between passes
• Colors seem misregistered, like a color print looking 'out of focus'
• Problem started after replacing a cartridge

Likely causes

• CommonPrint head alignment needs recalibration after a cartridge changeReplacing a cartridge can slightly shift the head's calibrated position, especially on inkjets with a removable head.
• CommonAlignment naturally drifting over time or useMechanical wear can gradually shift alignment even without a cartridge change.
• PossiblePrinter moved or bumped recentlyPhysical jostling can occasionally affect internal alignment on some models.

What to do

1. Open the printer's utility software (from the manufacturer, often accessible via printer properties or a dedicated app) and find the 'Print Head Alignment' or 'Calibration' tool.
2. Run the alignment utility, which typically prints a test page with numbered patterns.
3. Follow the on-screen instructions to select the best-aligned pattern number from the printed test page.
4. Run a second alignment pass if the first attempt doesn't fully resolve the issue.
5. Print a normal test document afterward to confirm text and lines now appear straight and properly registered.
6. If the utility can't be found through software, check the printer's own control panel menu for a built-in alignment option.

Tools and parts

• None

When to call a pro

This is a routine calibration task, not a hardware issue; if alignment can't be corrected through the utility or drifts again quickly and repeatedly, a technician can check for excess wear in the carriage mechanism.
