Epson SureColor T3475/T5475 for AutoCAD: Workgroup CAD Setup
Epson SureColor T3475/T5475 workgroup printers bridge compact CAD output and higher-volume production. Use separate 24- and 36-inch named Page Setups and a consistent Epson driver deployment.
Beginner takeaway: This is the workgroup middle: enough volume to justify standards, without the complexity of a production dual-roll fleet.
Where this family fits in CAD plotting
T3475/T5475 devices fit workgroups that need predictable 24- or 36-inch CAD production without the full complexity of a dual-roll production fleet. Standardize paper and driver deployment first, then compare physical lineweights with the office calibration sheet.
- Epson introduced T3475 as a 24-inch workgroup technical printer and T5475 as a 36-inch workgroup model.
- The family targets small- to mid-sized office CAD production.
- These models are designed for precise technical output and higher-capacity workgroup use than entry devices.
What matters in AutoCAD
- Create explicit 24- or 36-inch standards rather than one generic Epson Page Setup.
- Keep the same CTB/STB calibration sheet across devices so physical lineweights can be compared.
- Use the Epson driver media list as the source of truth for physical paper availability.

Beginner setup: create one reliable AutoCAD test Layout
Step 1 — Install the manufacturer driver first
Where: Epson support site / operating-system printer settings
Do this: Install the driver intended for the exact device and operating system. Confirm the printer works outside AutoCAD before building a PC3.
Check: A test page or manufacturer utility can reach the device.
Step 2 — Open one AutoCAD Layout
Where: Layout tab > PAGESETUP > Modify
Do this: Select the system printer or approved PC3, then choose the real paper/roll size used for the test.
Check: The intended media is visible and the orientation matches the title block.
Step 3 — Keep the sheet at real paper size
Where: PAGESETUP > Plot Area / Plot Scale
Do this: For a prepared Layout, use the Layout workflow and keep the paper output at 1:1. Let viewport scale control the model view.
Check: Plot Preview shows the complete border without Fit to Paper.
Step 4 — Preview before hardcopy
Where: Ctrl+P > Preview
Do this: Inspect border edges, rotation, lineweights and raster content before sending a physical job.
Check: The Preview is correct before the plotter driver becomes part of the diagnosis.
Step 5 — Create a controlled PC3 only when useful
Where: PLOTTERMANAGER / Page Setup
Do this: Save a PC3 when you need repeatable device-specific settings that differ from the Windows/macOS printer defaults.
Check: The PC3 is named by device + media/office standard, not by a vague name such as ‘Plotter 1’.
Paper, rolls and printable area
Use one default technical roll and keep exceptions in separate Page Setups. Standardize custom sizes by real dimensions, not by user-created names.
Check hardcopy margins when migrating title blocks from a different 24/36-inch plotter family.
Driver and PC3 strategy
Install the intended Epson system printer driver on each workstation or deploy it centrally, then map AutoCAD PC3/Page Setups to that queue.
Common CAD plotting problems with this family
| Symptom | Most likely hardware/driver layer | First check |
|---|---|---|
| Different workstations show different media | Driver mismatch | Standardize driver. |
| Lineweights differ from previous plotter | Device/media calibration | Use test sheet. |
| Batch uses wrong size | Page Setup inconsistency | Preflight layouts. |
| Printer slow on network | Queue/network | Test outside AutoCAD. |
What not to automate or assume
- Do not duplicate Page Setups by user name.
- Do not let every user create local custom paper sizes independently.
- Do not interpret advertised dpi as the AutoCAD lineweight standard.
Practical example
A T5475 replaces another 36-inch plotter and the physical lineweights look heavier. Keep the CTB and drawing unchanged at first; print the same calibration PDF on both devices and compare media/quality settings before deciding whether an office lineweight adjustment is actually needed.
Verification before a real issue set
- Run AutoCAD Plot Preview from the named Page Setup.
- Create one PDF and compare page dimensions and scale.
- Print that same PDF or one direct test plot on the intended media.
- Check the border on all four sides, one known dimension, lineweight hierarchy and orientation.
- Only then save the Page Setup/PC3 as the office standard for that device.

Frequently asked questions
Should I use Epson Raster or PostScript?
Use the driver path supported by your exact model and test your real CAD sheets. PostScript is not automatically the best choice for every AutoCAD drawing.
Can I keep an old Epson HDI driver?
Only in a compatible, tested legacy environment. For a modern OS, prefer the current manufacturer-supported driver unless you have a specific reason.
Does the scanner affect AutoCAD plotting?
No. On MFP models, print and scan are separate software/workflow layers.
