Our team at The Printer Repair Group of Baltimore recently completed HP printer repair in Baltimore for an HP LaserJet MFP M630 showing error 99.09.67 (not bootable). After HP had previously replaced the formatter, the device later reported a fuser error. We restored performance with a maintenance service and fuser replacement.
HP Printer Repair Baltimore – The Problem
The M630 intermittently failed to boot with code 99.09.67 and later alerted for a fuser fault. Staff also noted concern about slight noise from the new fuser after install. With over 400k lifetime pages, both the imaging subsystem and wear items were due for inspection.
Our Diagnosis
Our technician verified the replacement formatter, checked boot integrity, and inspected high-wear components. Given the page count and symptoms, we determined the device needed a full maintenance refresh and a new fuser to clear error states and stabilize output.
The Solution
We installed a new Fuser Main Kit (B3M77A), completed a maintenance kit service, and reset the maintenance counter. The printer passed functional tests and returned to service. We advised that mild break-in noise from a new fuser is normal and should diminish with use.
Key Takeaway
If your HP LaserJet M630 shows 99.09.67 or fuser errors, a combination of firmware/boot checks and timely maintenance (fuser & rollers) typically restores reliability. For general reference, see HP Support or review PCMag’s printer maintenance guide.
