## Claims

### Claim 1

A freestanding support, comprising:
a base;
parallel first and second sidewalls extending up from the base opposite one another a distance corresponding to a length of a Binary Ink Developer unit;
opposing first slots along a first edge of each sidewall, the first slots being configured to receive and suspend a Binary Ink Developer unit between the sidewalls; and
opposing second slots along a second edge of each sidewall, the second slots being smaller than the first slots and configured to receive and suspend a developer roller between the sidewalls.

### Claim 2 (depends on 1)

The support of claim 1, wherein the second edge is below the first edge.

### Claim 3 (depends on 1)

The support of claim 1, wherein:
the opposing first slots comprise two sets of opposing first slots along the first edge of each sidewall, each set of first slots being configured to receive and suspend a Binary Ink Developer unit between the sidewalls such that the support can support two Binary Ink Development units at the same time; and
the opposing second slots comprise two sets of opposing second slots along the second edge of each sidewall below the first edge, each set of second slots being configured to receive and suspend a developer roller such that the support can support two developer rollers at the same time.

### Claim 4

A freestanding support, comprising:
a base;
parallel first and second sidewalls extending up from the base opposite one another a distance corresponding to a length of a Binary Ink Developer unit;
opposing first slots along a first edge of each sidewall, the first slots being configured to receive and suspend a Binary Ink Developer unit between the sidewalls; and
scale markers along the base for comparison with print defects appearing in printed media.

### Claim 5 (depends on 4)

The support of claim 4, comprising opposing second slots along a second edge of each sidewall, the second slots being smaller than the first slots and configured to receive and suspend a developer roller between the sidewalls.

### Claim 6 (depends on 4)

The support of claim 4, wherein the scale markers comprise first scale markers along a first side of the base and second scale markers along a second side of the base opposite the first side.
