Ink Supplies Troubleshooting The printer consumes more gray ink ink than M C or Y This is not a problem and no action should be taken to correct this attribute of the printer In general the higher frequency of change is because Matte Black ink is the one that is used for lines and black objects in technical papers bond coated HW coated natural tracing paper etc which are the types of contents that are more commonly printed with this type of printer About gray ink The T Series Printers are the first HP Designjet technical products to include Gray ink One thing that users may notice is that Gray ink is used in higher quantities than Cyan Magenta and Yellow inks This happens because of the following reasons 1 Gray areas which are very typical in technical drawings can now be printed by using only Gray ink In the past these areas had to be printed by combining Cyan Magenta and Yellow inks This means that Gray ink is used more frequently than the rest of the inks C M Y which are now used less frequently so the difference in consumption is noticeable However overall the T Series Printers will actually need to use in total less ink to print gray areas than previous Designjet products 2 Soft colors can now be printed by combining C M and Y inks with Gray The addition of Gray ink softens the color improving transition areas It also allows printing soft colors by using less C M and Y These two types of co

51. system error Symptoms This type of 79 04 always occurs in heavy load conditions so the symptoms will always be similar to this pattern A printer that is being heavily used printing a project or in a reprographics environment produces 79 04 errors randomly forcing the user to reboot After rebooting the printer can be used without any issues for an extended period of time but if the workload is consistently high a random error will occur again The error can never be associated with a specific file The file that was being printed when the error occurred the last time can be printed without issues after reboot And a file that has been printed without issues several times can trigger the error in the future This error is very dependant of the workflow the customer has The most common user workflows have been extensively tested both by HP and by our beta sites so it is highly unlikely to see random 79 04 issues in these cases These random issues tend to occur in very specific corner cases and cannot be reproduced unless the exact conditions of the workflow are replicated They normally happen when sending files generated by external applications RIPs 3rd party drivers etc Workarounds and solutions Random 79 04 errors are by far the most complex ones to diagnose and to fix The only solutions available in these cases are 1 Identify the root cause either in the files or in the firmware and fix it in the code wh
