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.
For example, assume total costs at 400 units is $1,200, and total costs at 350 units is $1,020. The unit costs are $3.00 ($1,200/400) and $2.91 ($1,050/350). Because the unit costs differ at the two activity levels, the cost is not variable. By default since the cost is not fixed or variable, it is a mixed cost.otal variable costs vary in direct proportion to volume. In other words, the more units produced and sold, the higher the total variable cost. The unit variable cost is the same at every level of activity. Total variable cost is zero if no units are produced and sold.
