98
HP Printer
Severity: ModerateWhat Does This Error Mean?
Error 98 on an HP LaserJet means there is a problem with an installed memory module (RAM) in the printer. HP LaserJets have memory slots that allow you to add extra RAM for handling larger and more complex print jobs. Error 98 indicates a memory module is either incorrectly installed, incompatible, or faulty. This error prevents the printer from fully initializing.
Affected Models
- HP LaserJet 4
- HP LaserJet 5Si
- HP LaserJet 8100
- HP LaserJet 8150
- HP LaserJet series with upgradeable memory slots
Common Causes
- Aftermarket or incompatible RAM module installed in the printer's memory slot
- Memory module not fully seated in the slot during installation
- Corrupted memory module that passes initial contact but fails during the memory test
- Wrong memory type installed — HP LaserJets require specific proprietary memory formats on older models
- Damaged memory slot contacts in the printer preventing proper connection
How to Fix It
-
Turn off the printer and unplug it. Locate the memory expansion slot on the side or back of the printer (covered by a small panel). Remove any recently installed third-party memory modules.
Turn the printer on without the extra memory and check if Error 98 clears. If it does, the extra memory module is the problem.
-
Re-seat the memory module. Turn off and unplug the printer. Remove the module fully, wait 30 seconds, then re-insert it firmly until it clicks into place.
Even factory-installed memory can work loose over time due to vibration from everyday printer operation.
-
Check the memory module for physical damage — bent contacts, cracks, or burn marks. A damaged module must be replaced.
Hold the module by the edges and use a flashlight to inspect the gold contact fingers at the bottom edge.
-
If using a third-party memory module, verify it is compatible with your exact printer model. HP uses proprietary memory specifications on some LaserJet models. Check HP's compatibility guide for your printer.
Generic PC RAM usually will not work in HP LaserJets. Only buy memory modules specifically listed as compatible with your printer model.
-
If the original factory memory causes Error 98 and no extra modules are installed, the factory memory chip on the formatter board may have failed. This requires formatter board replacement or professional service.
Formatter board replacements cost $50 to $150 for older LaserJet models.
When to Call a Professional
Error 98 is usually a DIY-fixable memory issue. If you installed a memory upgrade recently, the new module is the first thing to remove and test. If the error appeared without any recent changes, the original factory memory may have failed. HP LaserJet memory modules cost $20 to $80 depending on capacity and model.
Frequently Asked Questions
Does Error 98 cause permanent damage to the printer?
No. Error 98 is a memory detection fault that stops the printer from initializing until the memory issue is fixed. The printer itself is not damaged by this error. Once the correct memory is installed and seated properly, the printer will function normally.
Can I run the printer without the extra memory?
Yes. HP LaserJets come with enough base memory to handle standard print jobs. Removing the added memory module and reverting to factory specs will allow the printer to work — just without the extra memory capacity. This is a valid workaround if a compatible replacement module is not immediately available.
How do I know how much memory my HP printer has?
Print a configuration page from the printer's control panel menu. The configuration page lists installed memory in the printer's current setup. Access this through the printer's menu — usually under Information or Reports.
