Express the costs of consumables (over $12,100) to operate printer services offered for free to Chem majors, over a period of 1.5 years. Does not include the cost of the $2.5K printer itself.

Current status, July 2014

Decision to continue not to account for use by student, much less meter use.

ChemIT has helped reduce costs, given this arrangement. Usage costs are over $1,000 less per year. And a new printer was bought at 1/4 to 1/5 the expected price.

(1) ChemIT has arranged for saving ~$1,000 per year by moving to Eastern service contract

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 (Dec 2012 - July 2014 (~17 months) from the oldest printer (Buckbeak); 40,000 from 2/14 to 7/14), that would be $5,292 ($3,736/yr). Service only if under warranty (new printer). Otherwise, for old printer, pay directly.
For the same volume, nowwe would have paid $3,850 (see below chart). For 17 months, that's $2,718/yr.
- That's a savings of $1,442 over 17 months, which is a savings $1,018/yr.

(2) New Xerox printer bought by ChemIT for less than 1/9th the expected price.

New printer, with warranty, was expected to cost $2,500. During the summer 2014, Michael Hint bought the 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. So price of printer was $1,925.22, not the expected $2,500.
This gives Lars's undergraduate lab two Xerox color printers. This new printer displaced a B&W HP printer, which went to Dan Lorey.

Summary

Consumables = (Ink + maintenance kits) + paper = $10,200 + $1,930 = $12,130 over 33 months.

This comes to about $4,411/year.

Data and analysis

Page counts	Dates	Count of months	Avg pages per months (including summers) Most uses is Jan/Feb. and Aug/Sept	At 1.53 cents/ page, for just ink (a consumable)	At 0.36 cents/ page, for just maintenance kit (another consumable)	Cost for both consumables (NOT paper)
300,000	May 2011 - Nov 2012	19 months	15,000 pages /month	$4,585	$1,080	$5,670
240,000	Dec 2012 - Feb 2014	14 months	16,000 pages/ month	$3,665	$865	$4,530
Total: 540,000	May 2011 - Feb 2014	33 months	15,430 pages/ month	$8,250	$1,945	$10,200

Hardware costs, including "consumable" maintenance kits

Printer's initial cost, including 3 year warranty: $2,500

Amortizing cost of printer over 540K pages printed comes to 0.46 cents per page.

Cost for maintenance kits, up to now: $1,945

10 have been installed for the most recent 240,000 pages, at $86.40 each: $864 + $1 = $865
Thus estimate we 1.25 additional kits (~12.5 kits) for the first 300K pages printed: $1,080

Thus, $4,445 spent so far on hardware, including maintenance kits.

Ink cost calculations

Total ink costs: $8,250

Usage Dec 2012 - Feb 2014

Ink Stick color	Use	6 Sticks per package	Cost per package (These are Michael Hint's costs; Lars may pay more?)	Total costs
Cyan	28	4.67	$69.65	$325.26
Magenta	24	4.00	$69.65	$278.60
Yellow	22	3.67	$69.65	$255.62
Black	76	12.67	$221.40	$2,805.14
			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.

Paper costs

Cost for paper, up to now: $1,930

0.575 cents per page, if buying cheap and you don't care about the environment.
Total of 335,000 sheets of pater used.
- 149,000 paper sheets used for 240,000 pages printed.
- Thus estimate that an additional 186,000 paper sheets used for previous 300,000 pages printed.
