94
HP Printer
Severity:What Does This Error Mean?
Error 94 is an ink color out of alignment error on HP OfficeJet and DeskJet printers. The printer detected that color alignment has failed or is needed. This usually happens after installing new ink cartridges or after a long period without printing.
Affected Models
- HP OfficeJet Pro 8000 Series
- HP OfficeJet Pro 9000 Series
- HP DeskJet 3700 Series
- HP OfficeJet Pro 6900 Series
- HP ENVY 5000 Series
Common Causes
- New ink cartridges were installed and the printer needs to realign the print heads
- A cartridge was not installed correctly and is slightly misaligned in its slot
- The print heads are clogged with dried ink, preventing proper alignment
- The alignment page printed during setup was scanned incorrectly by the printer
- A third-party or refilled cartridge is not fully compatible with the printer's alignment system
How to Fix It
-
Open the printer app on your computer or go to the printer's control panel. Find 'Printer Maintenance' and select 'Align Print Heads'.
The printer will print an alignment page. Make sure you have plain white paper loaded — using coloured paper will cause the alignment to fail.
-
Follow the on-screen instructions to scan the alignment page using the printer's built-in scanner (if it has one). The printer will analyze the page and adjust automatically.
If the alignment page has smears, streaks, or missing sections, the print heads may need cleaning before alignment will succeed.
-
Remove each ink cartridge and reinsert it firmly. Make sure each cartridge clicks into its slot.
A cartridge that is not fully seated can cause alignment errors. Even if it looks installed, press it in again to confirm.
-
Run the print head cleaning utility from the printer maintenance menu. Then try the alignment process again.
Print head cleaning uses a small amount of ink. Run it only once or twice — excessive cleaning wastes ink and can sometimes make clogs worse.
-
If you are using third-party or refilled cartridges, replace them with genuine HP cartridges and try the alignment again.
Third-party cartridges sometimes have slightly different chip profiles that cause alignment failures. Genuine cartridges are the most reliable test.
When to Call a Professional
If alignment repeatedly fails and you have tried multiple sets of genuine HP cartridges, the print head assembly may need cleaning or replacement. HP repair centers can perform deep print head cleaning or replace the assembly. On lower-cost printers, a new printer may cost less than the repair.
Frequently Asked Questions
Why does my printer need to align ink cartridges?
Ink cartridges have tiny nozzles that spray very precise dots of ink onto the page. Even a fraction of a millimetre of misalignment can cause blurry text or colour fringing. Alignment calibrates the cartridges so all colours line up perfectly, giving you sharp, accurate prints.
How often should I align my print heads?
Typically only when you install new cartridges or notice print quality declining. Most printers prompt you automatically when alignment is needed. You do not need to run alignment on a schedule — only when print quality is visibly affected.
My alignment keeps failing every time. What is wrong?
Repeated alignment failures usually point to one of two problems. Either the print heads are clogged and cannot print a clean alignment pattern, or a cartridge is defective. Try a deep clean cycle, then replace any cartridge that appears low or damaged. If the problem persists with genuine HP cartridges, the print head assembly may need professional service.
