HP 11.00.0X on a laser printer: internal clock error
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
The printer reports a problem with its internal clock. Set the date and time on the control panel each time you turn the printer on, and if the message keeps returning, ask an authorised HP service provider to check it.
Safety first
Stop and check this first
- Do not remove the side panel or touch the formatter yourself: HP's procedure requires disconnecting power first and the formatter is an electronics board for service.
Safe checks you can perform
- Set date and time
- Pattern after restarts
- Book service for the formatter checks
Leave these tasks to a qualified professional
- Do not attempt this professional task: Formatter cable check
- Do not attempt this professional task: Formatter replacement only if justified
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Formatter cable check
What they doThe technician turns the printer off, disconnects power, removes the right-side panel and checks that the formatter cables are firmly seated, as HP's procedure describes.
They must show youthe cables checked, the date and time held after a restart.
In writingwhat was checked and whether any cable was reseated.
Formatter replacement only if justified
What they doIf the message continues after the cable check, the authorised dealer or service representative replaces the formatter, as HP specifies.
They must show youthe result of the earlier steps and the printer holding date and time after the replacement.
In writingthe reason for replacement, the formatter reference and the cost.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Set date and time
- Who:
- you, from the control panel.
- How:
- set the date and time on the control panel, as HP indicates, each time the printer is turned off and on.
- Result that matters:
- the message clears and the time stays correct while the printer is on.
- If it clears:
- keep setting it after each power cycle and note how often it is lost.
- If the message stays even with date and time set:
- go on to booking service.
- Evidence to keep:
- photo of the code and the time shown after each restart.

Pattern after restarts
- Who:
- you.
- How:
- over a few days, note whether the date and time are lost every time the printer is turned off.
- Result that matters:
- a record of whether the clock fails at every restart.
- If it fails every time:
- the clock is not holding time; report it to service.
- If it rarely happens:
- note the dates for the technician.
- Evidence to keep:
- list of dates and whether the time was lost.

Book service for the formatter checks
- Who:
- you.
- How:
- contact HP or an authorised service provider with the model and the exact code, 11.00.01 or 11.00.02.
- Result that matters:
- a service visit for the formatter cable check.
- If the printer is under contract or warranty:
- ask how it is covered.
- If not:
- ask for the price before work starts.
- Evidence to keep:
- case number.

What it means
On the HP LaserJet Enterprise M604, M605 and M606, HP defines 11.00.01 and 11.00.02 as an issue with the printer's internal clock. The clock lives on the formatter, the main control board, and HP's steps are to reset the date and time, then check that the formatter cables are seated, then replace the formatter through an authorised dealer or service if the message continues. The code says the clock is not keeping time; it does not on its own prove the formatter must be replaced.

Symptoms and causes
Probable causes · in order
- Date and time lostCommon
HP's first step is setting the date and time on the control panel after each power cycle. If the message clears after that, the clock setting was the issue.
Evidence: HP LaserJet Enterprise M604-M606 Printers - 11.00.0x internal clock errors
- Formatter cable not seatedPossible
HP's second step checks that the seven formatter cables are firmly seated. This involves removing a side panel, so it belongs with service.
Evidence: HP LaserJet Enterprise M604-M606 Printers - 11.00.0x internal clock errors
- Formatter faultLess common
If the message continues after both steps, HP sends you to an authorised dealer or service representative to replace the formatter.
