NOTE Troubleshooting Lower image gloss directly after printing on HP High Gloss Photo Paper Lower gloss appearance of the print when the media is drying which gradually disappears to get the final gloss level (between 10 and 60 minutes depending on the ink density). Try the following: n Wait at least 60 minutes to achieve the high gloss appearance. 34" Rice Paper not supported Roll length is 34" (Non-standard) and the pinch wheels can't control edge of media causing ink smears and Printhead crashes in middle of prints with or without area fills. PRINTER LIMITATION - NO SOLUTION AVAILABLE. Cut Sheet rice paper loading failure Thin rice paper is sucked into the Center Platen grooves and Linear Blade Ridge. This implies that the friction between the Center Platen and the rice paper becomes higher than between the Overdrive wheels and the paper. This effect make it almost impossible to load the rice paper correctly because the Vacuum is too high. PRINTER LIMITATION - NO SOLUTION AVAILABLE. Worm marks on HP Coated media with light area fills Light bands (S-shaped) in Paper axis direction where light area fills are printed, causing unacceptable Image Quality defect. n Print the Service Configuration Print (⇒ Page 1-19) and check if the level of Humidity is very low (below 30%). Increasing humidity may help in reducing the severity of the problem. The media is causing the problem and NOT the Printer. Do not attempt to try and replace Printer parts to solve this problem.
