Cause

The unit is converted from mm or inch to pt in RIP processing of the EFI controller. At this time, a rounding error may occur because the number is indivisible.

If a rounding error occurs, the image position is misaligned by 1 pt (approximately 0.35 mm / 0.013").

If this problem occurs, the original image position is also misaligned, so this misalignment cannot be adjusted using the [Auto Image Adjustment] function of Intelligent Quality Optimizer IQ-501.

Option

Intelligent Quality Optimizer IQ-501, EFI controllers

Working time

10 minutes

Overview

This problem can be resolved by setting [Image Shift] in the printer driver or Command WorkStation (CWS).

Precautions

A misalignment between the front and back positions occur for several reasons.

Check whether the paper used for both sides adjustment is cut correctly.

Procedure

The following procedure shows an example for the Fiery color server.

1. When Intelligent Quality Optimizer IQ-501 is mounted, select [MACHINE] - [Paper Setting] - [Both Sides Adj.] - [AutoMeasure] on the Touch panel.

2. Correct the misalignment between image positions for each paper tray. [AutoMeasure] allows you to collectively adjust multiple paper trays, or output multiple charts to enhance the adjustment accuracy.

3. Open [Properties] of the job in the printer driver or Command WorkStation (CWS).

4. Set the shift amount in [Image Shift]. It is recommended that you shift the front side by 1 pt (approximately 0.35 mm / 0.013") in the paper feed direction.
