Canon has user-replaceable printhead. Users can replace the printhead in about 10 minutes. Epson requires a technician to schedule an onsite visit and costs about $ 1,200. The Epson head is very durable - but won't last forever. Canon thermal head tends not to clog. Epson printer heads tends TO clog. Canon heads will self-clean if it does clog. Epson's heads do not. Canon's thermal technology (heat) tends to keep the nozzles cleaner than the piezo-electric design Epson uses.
Variable Cost per Unit. If the number of units produced in the period is 1,000 then the variable cost per unit is calculated as follows. Variable cost/unit = Variable cost / Number of units Variable cost/unit = 92,600 / 1,000 Variable cost/unit = 92.60.
There is also a variable cost component related to running the machines on the factory floor. The fixed component in this example is $3,000 per month. The variable cost component is $10 per unit of output. Hence, at a production level of 500 units, the total electric cost is $8,000 [$3,000 + ($10 x 500)].ence, when 100 units are manufactured, the fixed cost per unit is $500 ($50,000 100). When 500 units are manufactured, the fixed cost per unit is $100 ($50,000 500). Relevant Range: The relevant range is the range of activity (e.g., production or sales) over which these relationships are valid.
