HP Printer Error Code 22 — What It Means & How to Fix It

What Does This Error Mean?

The error 22 means your HP printer experienced an I/O timeout. I/O stands for Input/Output — the printer stopped receiving data from the computer before the print job finished. The communication link between your computer and the printer was interrupted or too slow.

Affected Models

HP LaserJet Pro M400 Series
HP LaserJet Enterprise M600 Series
HP LaserJet Pro MFP M428
HP Color LaserJet Pro M200 Series
HP OfficeJet Pro 9000 Series

Common Causes

The USB cable between the computer and printer is loose, damaged, or too long
The network connection to the printer dropped during a print job sent over Wi-Fi or ethernet
The print job file is very large and the computer is sending data too slowly
The printer driver on the computer is outdated or corrupted
The printer's network settings have changed, causing it to lose connection with the computer

How to Fix It

If using a USB connection, unplug the USB cable from both ends and plug it back in firmly. Try a different USB port on your computer.

USB cables longer than 6 feet can cause communication problems. Use a shorter cable if possible.
If using a network connection, check that the printer is still connected to your Wi-Fi or ethernet. Print a network configuration page from the printer's control panel.

On most HP printers, you can print a config page from Setup > Reports > Network Configuration.
Restart both the printer and your computer. This clears any stuck print jobs and resets the communication channel.

Also clear the print queue on your computer. Go to Devices and Printers, right-click your HP printer, and select 'See what's printing.' Cancel all jobs.
Update your HP printer driver. Visit support.hp.com, enter your printer model, and download the latest driver for your operating system.

An outdated driver can cause timing issues that lead to I/O timeouts.
If the error happens with large files, try increasing the I/O timeout value. On the printer's control panel, go to Setup > System > I/O Timeout and increase the value.

The default is usually 15 to 30 seconds. Increasing it to 60 or 90 seconds gives more time for large jobs.

When to Call a Professional

The error 22 is a communication issue that does not require professional repair. You can fix it by checking cables, updating drivers, or adjusting timeout settings. If the problem persists after troubleshooting, contact HP Support at 1-800-474-6836. They can help diagnose whether the issue is with the printer's network interface.

Frequently Asked Questions

What does I/O timeout mean in simple terms?

Think of it like a phone call where one person stops talking for too long. The printer is waiting for the computer to send more data, but the data never arrives. After waiting too long, the printer gives up and shows the error.

Does this error mean my printer is broken?

No. Error 22 is a communication problem, not a hardware failure. The printer itself is fine — it just lost connection with the computer during a print job. Fixing the cable, network, or driver resolves the issue.

Why does this error happen more with large print jobs?

Large files take longer to transfer from the computer to the printer. If the transfer speed is slow and the timeout value is short, the printer may time out before receiving all the data. Increasing the I/O timeout setting gives the printer more patience to wait for large files.
