Email message on how to use the coffee maker
... we had a problem with the use of pre-ground coffee...:
Beans (never ground coffee) go in the righthand side.
Water goes only in the lefthand side water reservoir.
If you wish to use the PRE-GROUND COFFEE feature, rather than having the machine grind beans for you, you may place NO MORE THAN TWO LEVEL SCOOPS (see scoop in cupboard) of ground coffee in the ground coffee funnel (See 8 in Fig. 1, attached).
If you place any coffee in the ground coffee funnel you MUST press the "Pre-ground coffee" button (See h in Fig. 3, attached) on the front panel before you press the 1-Cup or 2-Cup buttons, otherwise the machine will attempt to grind additional coffee and will overfill the mechanism.
NEVER pour unmeasured ground coffee into the ground coffee funnel.
If you don't know how to use a particular feature of the machine, the instruction manual is in the cupboard next to it...
What is truly important
As I have suggested, coffee is one of the common fuels at PARC. So, people take it very seriously when something happens to the coffee maker.
Also a nice touch to include attached diagrams in the email.
Lucky I drink tea...
