IV. Printer Calibrations: User Calibrations Printer calibrations apply to the overall setup and calibration of the printer and mainly apply to service technicians. However, there are four basic calibrations that can be done by the operator and that can improve the performance of the printer. These calibrations are: 1. Media Feed Calibration - Calibrates the media advance accuracy. Visual and (for rigid media only) camera-assisted calibrations are available. For greater accuracy, follow these tips: • Record the initial Media Feed Number (MFN) before making any changes. • Use a lightweight rigid media such as Foam Board with the associated media wizard settings. • Perform the calibration process 3 times or more. • Use the 900 mm (34 inch) pattern. 2. Manual BiDi Registration - Ensures that every working jet fires at precisely the same location (regardless of the direction of carriage travel). 3. Manual Printhead X Calibration - Ensures that the printheads are in alignment relative to each other. 4. Manual Jet Mapping - Substitutes missing jets for working jets. Manual calibrations are suggested for more reliable and repeatable results. Please, refer to the HP Scitex FB550 and FB750 Printers - User's Guide for a detailed explanation of these four routines. 9

Printer Calibrations: User Calibrations
Printer calibrations apply to the overall setup and calibration of the printer and mainly apply to service
technicians. However, there are four basic calibrations that can be done by the operator and that can
improve the performance of the printer. These calibrations are:
1.
Media Feed Calibration
- Calibrates the media advance accuracy. Visual and (for rigid media only)
camera-assisted calibrations are available. For greater accuracy, follow these tips:
•
Record the initial
Media Feed Number
(MFN) before making any changes.
•
Use a lightweight rigid media such as Foam Board with the associated media wizard
settings.
•
Perform the calibration process 3 times or more.
•
Use the 900 mm (34 inch) pattern.

Manual BiDi Registration

(regardless of the direction of carriage travel).

each other.
