2.4.3 Plot for escalation only
To print this test plot go to Menu List>2. Image Quality Plots>2.4 Printheads Health>2.4.3 Only For
Escalations. There are two identical plots to this test and each plot has three parts to it. The first plot refers
to the rear printheads (number 1, 3, 5), while the second plot refers to the front printheads (2, 4, 6).
This plot is only printed at the request of the HP Division, or in case further help is required and there is
need to escalate an image quality issue to HP Division.
2.5 Geometry Check
The Geometry check print test is a simple template designed to check the printer’s length accuracy and
figure distortion performance. To print this test plot go to Menu List>2. Image Quality Plots>2.5 Geometry
Check.
If a customer complains that there is an issue with a plot they are printing, this standard template can be
printed and referred to by both the customer and HP as a single point of reference.
The plot consists of a 7x7 matrix of rectangular boxes. By default, each single rectangle corresponds to
a DIN A4 sheet size (210mm x 297). Based on this, the total printed plot length should be about 2.07
meter (approx. 82”) and 1.47 meters (approx. 58”). However the actual dimensions will highly depend
on what settings have been defined for the Media Advance.
Each point in the matrix can be identified by means of a letter in the X axis and number in the Y axis.
There is an arrow in the plot close to the point ‘A1’ to show the printing direction.
The method of evaluating the geometric performance is the following:
1. Select an area on the matrix to evaluate for accuracy and dimensional integrity. The template is
designed so you can measure anything from an A4 sheet upwards to any probable dimension.
2. Place the printed plot on a flat surface. This will minimize any wrinkles before proceeding with the
process.
