8.When you are satisfied with the graytone image quality, print one or two cards with Wedge_1.bmp to test for ribbon wrinkling. This image is the densest possible process black, meaning that on all three passes (Y, M and C) one end of the printhead is fully “on”, while the other end is “off”, a sure way to induce wrinkling if there is the slightest tendency. Wrinkling may be a head angle issue (more clockwise than it should be), but it may equally result from too high a ribbon

torque, page TN4-x.Check the torque before readjusting the head.

9.When you are satisfied that ribbon wrinkling is under control, print one or two cards with Wedge_2. bmp, this being the same triangle flipped so that its black area starts full width.

10.As a final test, run Portraits.bmp to test for skin tone realism, etc.

Data

Ribbon Panel Detect: The current reading of the color ribbon sensor (High = black, Low = not black).

Panel Threshold: The current value of the detection threshold for the color ribbon. Above this value is termed “black”, below this value is termed “not black”.

Ribbon Encoder Count: The pulse count from the motion sensor (following page) from start to finish of the most recent YMCK panel set paid out from the ribbon supply roll.

Printhead Voltage: Should be about 24V.

Printhead Temperature: Temperature ceiling 70°C (above that temperature, printing is stopped until the head cools)

Printhead Lift (logic states): 0 = head raised, 1 = head down (see photos on following page)

Adjustment

Horizontal (X) Offset (Pixels): Moves the image along the length of the card. Used to center the image on the card.

Vertical (Y) Offset (Pixels): Moves the image up and down. Used to center the image on the card.

Black Panel - Speed : The printer was characterized in manufacture at a specific speed. Changing this speed will force the printer to use estimated energy values, and is not recommended.
