Current status, July 2014
Decision to continue not to account for use by student, much less meter use. But still managing to save ~$1,000/ year through two main changes:
(1) During the summer 2014, Michael Hint bought a $1,925.22 printer for $256.56.
- Did this through loyalty rebate ($1,443.91) and trade-in ($224.75) of (old, broken Abruna) printer to Xerox.
- Did not buy the extra warranty (~$500 more?), since under Eastern service contract.
- This gives Lars to Xerox color printers. This new printer displaced a B&W HP printer, which went to Dan Lorey.
(2) We are now on Eastern service contract, so our consumables and service are fixed, and less.
- We were paying about 1.89 cents per page for ink and maintenance kit replacement, on average. So for 280,000 pages, that would be $5,292. Service only if under warranty (new printer). Otherwise, for old printer, pay directly.
- For the same volume, now we would have paid $3,850 (see below chart), a savings of $1,442.
| Type of printing | Eastern's charges, per page | Page counts As of 7/24/14 | Costs $ |
|---|---|---|---|
| B&W, or little color | 0.7 cents | 200,000 | 1,400 |
| More color | 2.5 cents | 65,000 | 1,625 |
| Full color | 5.5 cents | 15,000 | 825 |

| Total ink costs for 240K pages: | $3,665 |
- $3,665 for 240,000 pages comes to 1.53 cents per page, on average.
- Thus, estimate that an additional 300,000 pages used previously (1.25 as much again) would cost about $4,585.
