6 Troubleshoot s ubstrate issues The substrate c annot be loaded success fully ● A substrate cannot b e loaded unless all pri nter subsy stems (e.g. the ink syste m) are r eady.
3. If fe asible, man ually mo ve the c arriage s lowly and c arefully to the side, a way from the su bstrate. If thi s is not fea sible becau se of the severit y of the jam , try rais ing the car riage beam to it s maxi mum hei ght.
The substrate sticks to the p laten When the sub strate sticks to the platen, the most lik ely cause s are exce ssive heat and ex cessiv e vacuum . Therefore, try decreasing the dr ying tempe rature or the va cuum. For info rmation on how to adjust printer s ettings, see the User 's guide .
7 Troubleshoot print-quality issues Gene ral advi ce When you hav e any print-qu ality prob lem: ● To achi eve the best performan ce from your prin ter, use onl y genuine HP supplies an d accesso ries, whose re liability and performanc e have been thor oughly test ed to give trouble -free per formance and best- quality pr ints.
If the re are thi n white li nes across the width of the su bstrate: 1. From the HP In ternal Print Se rver, clean and check the pr intheads , and check for b locked nozzles . ● If there are bloc ked noz zles, incr ease the numb er of pa sses. ● If there is a s ubstrate-ad vance p roblem, decrease the substr ate-adva nce sett ing.
If the back s ide of the subs trate varies in c olor or sh ade (for in stance, if so mething has been printed on it), you may see ban ding in p arts of your print be cause th e substr ate-adv ance se nsor ha s becom e confuse d.
Colors are misaligned h orizontally 1. Ensure that the s ubstrate is not skew ed. If there is any skew, r eload the substra te to cor rect it. 2. Check th e carriage beam po sition. I f it i s high and the s ubstrate ty pe doesn 't requi re a hig h positio n, lower it.
a. Incr ease the number of passe s. b. Increase the dr ying tempe rature. c. Decrease t he ink l imit. For informatio n on how to a djust printer s ettings, see the User's guide . The print is smudged This indi cates t hat the ink i s not dry. The characteri stics of t he substr ate may have ch anged.
Colors are inaccurate 1. Check tha t the sub strate ha s been correctly loaded. 2. Check tha t the load ed subst rate is the same as the s ubstrate s elected i n the HP Intern al Prin t Server. 3. Check that the ICC pr ofile us ed by the R IP is correct for the load ed substrate .
8 Troubleshoot ink cartridge and printhead issues Cannot insert an in k cartridge 1. Use the correct procedure to change ink cartridges , through the fron t panel. See the User 's gui de . 2. Check that th ere is no obstruct ion in th e ink car tridge connector.
a. Turn off the printer. b. Place a piece o f paper u nderneath the car riage to collect any dir t that falls through. c.
