HP C3170A service manual

I need service manual for very old plotter HP C3170A

@stilian1,

Welcome to our HP Community forum!

Here’s what I’ve been able to pin down:

• The EMPR Australia parts listing for the DraftPro Plus explicitly shows the service manual as C3170-90000 (and the user/setup guides C3170-90031/-90032/-90036). It’s a legacy/“request quote” item, but the part numbers are confirmed there: EMPR Australia

• The EMPR New Zealand mirror has the same callouts and even a “Self-paced training kit” that includes the service manual -again confirming C3170-90000 for DraftPro Plus (C3170/3171A): store.emprgroup.co.nz

• HP’s own (Japanese) support index also lists the DraftPro Plus (C3170A/C3161A) user guides by part number (C3170-90031 English). It doesn’t host PDFs, but it’s official corroboration of the document families: HP Support

• If you just need technical reference while we hunt the exact C3170A scan, the HP 7540A DraftPro Hardware Support Manual (07570-90000) is online and very close mechanically/electrically to the Plus lineage -handy for troubleshooting belts, carriages, grit wheels, encoders, etc. (201-page PDF on Internet Archive): Internet Archive

 

What this means for getting the manual:

• There is an official HP service manual for the C3170A, part C3170-90000—the EMPR listings prove existence, even if they don’t expose a downloadable PDF. EMPR Australiastore.emprgroup.co.nz

• A freely available scan of C3170-90000 has not surfaced anywhere in the archives I checked (bitsavers, Archive.org, HP museum sites). I did find the closely related DraftPro service docs (07570-90000) which can fill gaps meantime: Internet Archive

 

Next best steps (that usually work for legacy HP docs):

1. Email EMPR (AU or NZ pages above) and ask if they can supply a digital scan of C3170-90000 or sell a photocopy -cite the exact part number so it routes correctly: EMPR Australiastore.emprgroup.co.nz

2. Post a request in the Vintage HP/HP-GL communities (e.g., VintHPcom @ groups.io) -there’s some prior chatter specifically about C3170A schematics and owners sometimes share scans privately: Groups.io

3. Use the HP 7540A DraftPro Hardware Support Manual now for service procedures that are shared across models (belt replacement, carriage/encoder checks, calibration).

Hope this was helpful.

Kind Regards,
