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.
Then you plot a variable cost line from this point, which will, in effect, be the total costs line. This is because the fixed cost added to the variable cost gives the total cost. To calculate the variable cost, you multiply variable cost per unit x number of units.In this example, you can assume that the variable cost per unit is Â£2 and there are 2,000 units = Â£4,000. Graph showing the breakeven point of a business. Once you have done this you are ready to plot the total revenue line.hen you plot a variable cost line from this point, which will, in effect, be the total costs line. This is because the fixed cost added to the variable cost gives the total cost. To calculate the variable cost, you multiply variable cost per unit x number of units.
