Symptoms
Blotchy area fills. (Print?Quality Plot ' page 8?56 1. - Area Fills.) (See also ' User's Guide, chapter 4.)
Product Fault
DAn incorrect media?type setting has been selected on the front panel and does not correspond to the media being used.
Media Fault
The ink is incompatible with the media and does not spread uniformly through the area fill.
Solutions
One or both of the following actions may be appropriate to solve an uneven?fill?density problem:
DChange the media?type setting on the front panel.
DUse a more suitable media type.
DIf the problem is occurring in black area fills on color plots printed in Normal print?quality mode, then use Best print?quality mode instead.
LightfastnessDrawings plotted with the color cartridges 51650C, 51650M, and 51650Y fade when exposed to light. Colors become less vivid and less bright, and change over time:
DUnder direct sunlight: After between 3 and 10 hours.
DUnder office light: After about 20 days.
DLaminated and under office light: After about 24 days.
The use of some non?HP media types improves the lightfastness.
Strict lightfastness is NOT necessary for the large majority of HP DesignJet 250C customers, but it will become important in the future for the large?format printing (LFP) market. HP is working on the development of a new set of inks.
SpraySymptoms
Smaller dots of sprayed ink located around the point at which the required dot is placed.
Product Fault
The cartridges are positioned too far from the media.
Solution
Adjust the nozzle?to?media distance. (Details ' chapter 7.)
