Canon imagePROGRAF AutoCAD Troubleshooting: Scale, Clipping and Color
When a Canon imagePROGRAF plot is wrong, identify whether the first bad stage is AutoCAD Preview, the PDF, the Canon driver or the physical plotter. That single decision prevents most random setting changes.
Start with this rule: Use Preview → PDF → paper as three separate checkpoints.
Why this problem happens
Scale and plot-style problems can begin in AutoCAD, while roll selection, hardware margins and driver color/media behavior can begin only after the file leaves AutoCAD.

Step-by-step workflow
Step 1 — Check Preview
Where: AutoCAD
Do this: Run Preview from the production Page Setup.
Check: Know whether problem exists before output.
Step 2 — Create PDF
Where: AutoCAD PDF
Do this: Use same Layout to create a baseline.
Check: Compare scale/content.
Step 3 — Print PDF to Canon
Where: PDF viewer
Do this: Use Actual Size and intended media.
Check: Separate Canon driver from AutoCAD.
Step 4 — Compare direct AutoCAD plot
Where: Canon queue
Do this: Send same Layout directly.
Check: Identify rendering/path difference.
Step 5 — Fix first wrong layer
Where: Only that layer
Do this: Change one setting and retest.
Check: Cause is proven.
How to tell which layer is responsible
| Symptom | Most likely hardware/driver layer | First check |
|---|---|---|
| Preview colored | CTB/STB/AutoCAD | Fix plot styles. |
| PDF correct, Canon color wrong | Canon media/driver | Check driver color/media setting. |
| PDF correct, paper clipped | Hardware margin | Check printable area. |
| Only direct AutoCAD plot wrong | AutoCAD-to-driver path | Rebuild/verify Page Setup/PC3. |
Settings worth standardizing
- Three-stage diagnostic method.
- Approved Canon queue and media.
- Known-good PDF calibration.
- Documented direct-vs-PDF print policy.
Common mistakes
- Changing CTB when only the physical driver is wrong.
- Using Fit to Paper to hide a Canon margin problem.
- Changing the DWG because one printer queue is misconfigured.
When to stop troubleshooting AutoCAD
Once you find the first wrong stage, stop changing earlier stages that are already proven correct.

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.
