Question:
I have an HP OfficeJet Pro 6978 and must replace the scanner or ADF glass. Will the HP Scanner ADF Glass Assembly – 1KR57-40008 fit my printer?
Answer:
Regarding your question, the HP Scanner ADF Glass Assembly (Part Number: 1KR57-40008) is a specific component used in a limited number of HP printer models. While it’s a great replacement part, it does not appear to be compatible with the HP OfficeJet Pro 6978.
The 6978 model uses a different scanner glass configuration and does not utilize the 1KR57-40008 part number for its ADF (Automatic Document Feeder) glass assembly. TThus,installing this specific part in your printer lwill likely notwork, as the form factor and mounting design wwill notmatch.
You can still do that if you want to replace just the glass—either the flatbed or ADF strip. We offer replacement scanner glass cut to size. Check the length and width of the glass on your unit and our available glass stock for a suitable match. Replacing just the broken or scratched glass is much more affordable and practical than replacing the entire assembly.
If you're unsure of the part number, it’s always a good idea to:
-
Remove the glass assembly (if comfortable doing so) and look for part number labels on the underside.
-
Refer to your printer’s service manual or parts diagram to confirm compatibility.
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. Getting your printer to drop off may take a few weeks. Our services are structured to repair a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.
