99.09.6X
HP 99.09.6X on a laser printer: hard disk or SSD error
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
The printer reports a problem with its hard disk or solid state drive (99.09.64, 65, 66 or 69). Turn it off and on to clear the message. If it persists, the drive installation must be checked by IT or an authorised service provider.
Safety first
Stop and check this first
- Do not remove the formatter or the drive yourself: HP describes power disconnection and an ESD sensitive part, which is work for IT or an authorised service provider.
Safe checks you can perform
- Note the exact code
- Power cycle
- Hand over to service
Leave these tasks to a qualified professional
- Do not attempt this professional task: Drive reseat
- Do not attempt this professional task: Drive replacement if the error persists
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.
Drive reseat
What they doThe technician turns off the printer, disconnects cables and power, removes the formatter and reinstalls the hard disk or SSD, as HP's procedure describes, taking ESD precautions.
They must show youthe printer starting without 99.09 after the reseat.
In writingwhat was done, the exact code and the result.
Drive replacement if the error persists
What they doIf the error remains after reseating, the drive is replaced through HP technical support, as HP states.
They must show youthe error before, the reseat result and the printer starting after the new drive.
In writingthe drive reference, the reason and whether stored data or settings were lost.
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.
Note the exact code
- Who:
- you, no tools.
- How:
- write down whether the panel or the Embedded Web Server shows 99.09.64, 99.09.65, 99.09.66 or 99.09.69.
- Result that matters:
- the exact code, which separates a missing drive, corrupted data and a failed drive.
- If it is 99.09.66:
- tell service the drive may be disconnected.
- If it is 64, 65 or 69:
- give the exact code to service.
- Evidence to keep:
- photo of the code.

Power cycle
- Who:
- you.
- How:
- turn the printer off and back on, as HP indicates, and wait for it to start.
- Result that matters:
- the printer starts without a 99.09 message.
- If it starts:
- note the date; the error was transient.
- If the message stays:
- stop here and contact IT or HP service.
- Evidence to keep:
- date, time and whether it returned.

Hand over to service
- Who:
- you.
- How:
- contact HP or an authorised service provider with the model, serial number and exact code.
- Result that matters:
- a service visit for the drive check.
- If the printer stores jobs or settings you need:
- ask service whether they can be kept.
- If it is under contract:
- ask how the drive is covered.
- Evidence to keep:
- case number.

What it means
On LaserJet Enterprise M551 to M830 models, HP lists 99.09.64 disk nonfunctional (fatal disk failure), 99.09.65 disk data error (data corruption), 99.09.66 no boot disk (drive not installed, not connected or failed) and 99.09.69 unknown boot disk error. The drive is on the formatter, and HP's steps are a power cycle, then removing and reinstalling the drive, then replacing it through HP if the error persists. The code points to the storage drive, yet reseating can clear it, so it alone does not prove the drive is dead.
Warnings and stop conditions
- Mediumeditorial warning
Do not remove the formatter or the drive yourself: HP describes power disconnection and an ESD sensitive part, which is work for IT or an authorised service provider.

Symptoms and causes
Probable causes · in order
- Transient boot errorPossible
HP's first step is to turn the printer off and on. If the message does not come back, the error was transient.
Evidence: HP LaserJet and Color LaserJet Enterprise M551, M575, M712, M725, M750, M775, M630, M806 and M830 Series - 99.09.64, 99.09.65, 99.09.66 and 99.09.69 Errors
- Drive not seated or connected (99.09.66)Possible
HP lists a drive not installed or not connected properly among the causes of 99.09.66. Reseating it, a service task, distinguishes this from a failed drive.
Evidence: HP LaserJet and Color LaserJet Enterprise M551, M575, M712, M725, M750, M775, M630, M806 and M830 Series - 99.09.64, 99.09.65, 99.09.66 and 99.09.69 Errors
- Data corruption (99.09.65)Possible
HP defines 99.09.65 as disk data corruption, which differs from a missing or failed drive.
Evidence: HP LaserJet and Color LaserJet Enterprise M551, M575, M712, M725, M750, M775, M630, M806 and M830 Series - 99.09.64, 99.09.65, 99.09.66 and 99.09.69 Errors
- Failed driveLess common
If the error persists after reseating, HP states the disk drive needs to be replaced.
