Seaory S25 / S26 / S28 — How to Print a Test Card (and Read the L, T and S Values)
Seaory support · Setup

Updated September 14, 2026

The test card (Seaory calls it the Print Test Chart) prints straight from the driver: no Bodno software, no design file. It confirms the printer, ribbon and driver are all talking, and its L and T scales tell you whether the print is aligned to the card edge.

Time 2 minDifficulty EasyYou need One blank card
Quick answer

Windows: Printing preferences → Tool → Position Calibrate → Print Test Chart. Mac: Printer Utility → Print position calibration → Print Chart.

Print a driver test chart on Windows or Mac to check printer operation. This is a diagnostic chart, not a badge created in Bodno software.
WindowsMac

Before you start

  • S25: have one blank card ready for the manual feeding slot. S26/S28: load cards in the input hopper with the weight plate on top. See the loading videos for your model.
  • Ribbon installed, cover closed, printer on and connected: S25 by USB; S26/S28 by USB or Ethernet.
  • You do not need Bodno software open. The test card is a driver function.

On Windows

1
Open the printer's Printing preferences
Settings→Bluetooth & devices→Printers & scanners→Seaory printer→Printing preferences
2
Open the Tool tab and click Position Calibrate

A small window called Print Position Calibrate Tool opens. It shows the L, T and S values (all 0 on a new printer).

Tool→Position Calibrate
3
Click Print Test Chart

The printer feeds a card and prints the chart. It uses one print from the ribbon, like any other card. Click Exit when it is done.

Print Test Chart
Windows driver: Tool tab → Position Calibrate → Print Test Chart.
Windows driver: Tool tab → Position Calibrate → Print Test Chart.
4
Read the card

A full chart with the L and T scales along the short edges means printer, ribbon and driver are all working. What the scales mean is covered below.

On Mac

Different window, same button. The Mac driver puts its tools in the Printer Utility.

1
Open the Seaory printer utility
System Settings→Printers & Scanners→Seaory printer→Utility→Open Printer Utility
2
Choose Print position calibration, then Print Chart

The same L, T and S values are shown. Leave them alone for now.

Print position calibration→Print Chart
Mac printer utility: Print position calibration → Print Chart.
Mac printer utility: Print position calibration → Print Chart.
3
Read the card

Same chart, same meaning.

What the test chart tells you

The chart prints a ruler at each short edge of the card, with an arrow at 0. L is the edge where printing starts, T is the edge where it ends. On a correctly aligned printer both 0 arrows sit exactly at the card edge. If there is a gap between a 0 line and the edge, the print image is offset in that direction, and you will see it as a white edge on real cards.

Seeing a white edge?

That is what the L and T values are for. White Edge on the Short Side of the Card walks through reading the chart and moving the value safely.

If the test card does not print

What you see Do this
Card does not feed S25: check that one card is presented at the manual feed slot. S26/S28: separate and reload the cards, with the weight plate on top. Follow the model-specific loading guide.
Ribbon error on screen Code 48: calibrate the ribbon LED. Code 45: ribbon missing guide.
Printer offline or not found USB: plug straight into the computer, not a hub. S26/S28 over Ethernet: check the network setup.
Blank card comes out The ribbon is not engaged. Reseat the cartridge, close the cover firmly, calibrate the ribbon LED, try again.

Questions about this

01 Does the test card use up a ribbon panel?
Yes. It prints like any other card, so it consumes one print from the ribbon.
02 Can I print the test card from Bodno software?
You do not need to. It lives in the printer driver, so it works even before Bodno is installed. That makes it the quickest way to prove the printer itself is fine.
03 What are the L, T and S values for?
They set where the print image lands on the card. L is the short edge where printing starts, T is the short edge where it ends, and S handles the other direction. You adjust L or T when cards come out with a white margin on a short edge.
04 The chart printed but one 0 arrow is broken.
That is an uneven card edge rather than a printer setting. Take a card from a different part of the stack and print the chart again.
05 Does this work on the R330 / R660?
The R-series driver has the same Position Calibrate tool in its Tool tab. The screens above are from the S-series driver.
