Method of compensating sheet feeding errors in ink-jet printer |
摘要 |
A method of compensating a sheet feeding error in an ink-jet printer includes printing a test pattern on the sheet; scanning the printed test pattern using the image sensor and measuring a distance W1 between a starting point X1s and an ending point X1e of the test pattern; driving the feeding roller and moving the sheet to a set distance Hm so that the set distance Hm is shorter than a length of the test pattern in a sheet feeding direction; scanning the test pattern using the image sensor and measuring a distance W2 between a starting point X2s and an ending point X2e of the test pattern; calculating a distance H, along which the sheet is actually fed, from a difference between the distances W2 and W1; calculating a feeding error E of the sheet from a difference between the feeding distance H and the set distance Hm; and compensating for the sheet feeding error E at the set distance Hm.
