For consistent printing of quality mailpieces, maintain your hardware according to the manufacturer’s approved procedures, using authorized parts and materials. For inkjet printers:
 |
Confirm that the height (throw distance) of the print head is within manufacturer specifications. Be particularly cautious of pieces of varying thicknesses. |
|
Ensure that the material transport moves the mailpiece smoothly, squarely, and consistently under the inkjet head before starting production. |
|
Make certain the encoder (tachometer) is operating smoothly and without vibration. |
The goal of the encoder is to accurately reflect the piece motion under the inkjet head. Loose or tight transport belts, excessively worn encoder wheels, or improperly placed encoder wheels will result in significantly degraded print performance.
