What usually causes it
- The cartridge may be for a different Lexmark family or region/variant.
- A supply can be physically installed but still fail the printer's compatibility check.
- The code is about cartridge support, not a driver, network, or paper problem.
What to try
Check the cartridge part/compatibility
Compare the installed supply with the cartridge specified for the exact printer model.
Remove and reinstall only if it is the correct supply
Seat it using the normal user replacement procedure.
Replace an unsupported cartridge
Use a cartridge listed as compatible with the model.
Retry the original print
After the printer accepts the cartridge, resend the job and confirm the code is gone.
After each corrective action
Retry the same operation that produced 32.40z. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If 32.40z appears with a supply that is definitely listed for the exact model, record the cartridge details and contact Lexmark/support rather than forcing it.
When service may be needed
Do not defeat cartridge recognition or modify printer firmware as a workaround.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
