I think that I have found a bug, perhaps the bug. In "Positive slide" txl = tyl (or in C-speak txl == tyl). That is the OPT_TL_X (25) and OPT_TL_Y (26) commands send the same value. The scanner accepts these and later reports them back. But it is not suprising that it may report an error when asked to scan nothing. But I may be misunderstanding the logs. If not it obviously suggests a line copied but then not fully edited somewhere... Here are extracts from logs: Bad === sane_epson2_control_option: action = 1, option = 25 [19:10:55.046283] [epson2] setvalue: option = 25, value = 0x7ffec352cb94 [19:10:55.046292] [epson2] setting size to 0.141098 <==== [19:10:55.046304] [epson2] setvalue: end [19:10:55.046314] [epson2] sane_epson2_control_option: action = 1, option = 26 [19:10:55.046323] [epson2] setvalue: option = 26, value = 0x7ffec352cb94 [19:10:55.046330] [epson2] setting size to 0.141098 <==== Good ===== sane_epson2_control_option: action = 1, option = 25 [19:08:50.561070] [epson2] setvalue: option = 25, value = 0x7ffcc93f2624 [19:08:50.561074] [epson2] setting size to 6.071701 <?????
