Canon imagePROGRAF Driver and PC3 Problems in AutoCAD
Canon imagePROGRAF driver changes can alter device names, media catalogs and paper behavior. Diagnose the queue and driver before rebuilding every AutoCAD Layout.
Start with this rule: If the problem appeared after a driver/OS change, compare the printer environment before editing the DWG.
Why this problem happens
Page Setups can retain a PC3 or queue mapping that no longer matches the active Canon driver. Media definitions can also change when the driver or Canon Media Configuration data changes.

Step-by-step workflow
Step 1 — Verify Canon queue
Where: OS printer settings
Do this: Print a simple test page.
Check: Base printer works.
Step 2 — Compare driver versions
Where: Working vs failing PC
Do this: Record exact driver/device name.
Check: Environment difference is known.
Step 3 — Open AutoCAD Page Setup
Where: PAGESETUP
Do this: Check queue/PC3 and paper.
Check: References match current driver.
Step 4 — Refresh/recreate PC3
Where: PLOTTERMANAGER
Do this: Create a clean controlled mapping if necessary.
Check: Invalid device warning disappears.
Step 5 — Retest media and border
Where: Preview + hardcopy
Do this: Check scale and edges.
Check: Production setup is restored.
How to tell which layer is responsible
| Symptom | Most likely hardware/driver layer | First check |
|---|---|---|
| PC3 missing printer | Queue renamed | Remap/recreate. |
| Paper disappeared | Media catalog changed | Refresh Canon media/driver. |
| Orientation differs | Driver custom properties | Compare Canon + AutoCAD orientation. |
| One PC wrong | Deployment mismatch | Use controlled driver/PC3 versions. |
Settings worth standardizing
- Driver release/change log.
- Canon media-profile update process.
- PC3 naming standard.
- Post-update calibration.
Common mistakes
- Copying a PC3 without installing the same Canon driver.
- Assuming the latest driver keeps every legacy media name.
- Maintaining multiple conflicting queues for one physical plotter.
When to stop troubleshooting AutoCAD
If one workstation alone is wrong, fix that environment first; do not modify the project DWGs.

Frequently asked questions
Should I troubleshoot Canon software before AutoCAD?
Only if the printer/driver is not working at the operating-system level. Otherwise use the Preview→PDF→paper sequence.
Should I create a separate PC3 for each paper size?
Not necessarily. Named Page Setups can hold paper choices while one controlled PC3 holds device-specific overrides.
Can a driver update change paper names?
Yes. Revalidate media lists and Page Setups after driver/media configuration changes.
