) on st4905 reacts in a similar manner as experience by the @The Hat when clearing the waste pads prompting to print eeprom instead and setting the counter value does nothing, extended nozzle checks work fine though.There are mentions of other service tools on that chinese site however from the newer service tools only 4905 4904 and 3900 having downloads available.I just noticed on the site that most post that show examples of printers having their counters cleared run on earlier firmwares the same thing noted by @Pavel maybe firmware updates change the service mode that makes the service tool call up the wrong function or vice versa? Attached st4904 that i havent even scanned for viruses ; runs on a spare windows pc fine although not much tests done with the 5620 as i absentmindedly service locked it with st4720
.will upload 3900 as well for those who want it maybe as soon as i complete the three part download (the site gives only a single download per day until the account has enough helpful posts to be upgraded although the sign up page is simple enough to work although the capcha maybe still be broken and make siign up impossible)
Norton's Security deleted the exe file within the zip when scanned. File marked as heuristic malware Heur.AdvML.B, a fairly nebulous designation and not necessarily malware. The dll file was not marked as malware unlike one of the other dll's from a previous Service Tool.
